Cinema Love is a stunning and sweeping debut novel about gay men in rural China, the women who marry them, and what happens to them when their secrets are revealed.

*A stunning and compelling novel for fans of PACHINKO, BROKEBACK MOUNTAIN, and SHUGGIE BAIN* 'The pages crackle with the tension of a Hollywood thriller . . . an enticing, engaging read' The Times 'Cinema Love is not just an extraordinary debut but a future classic' Jessamine Chan, author of The School for Good Mothers For over thirty years, Old Second and Bao Mei have cobbled together a meagre existence in New York City's Chinatown. But unlike other couples, these two share an unusual past. In rural Fuzhou, before they emigrated, they frequented the Workers' Cinema, where gay men cruised for love. While classic war films played, Old Second and his fellow countrymen found intimacy in the privacy of the Workers' Cinema's screening rooms. Elsewhere, in the box office, Bao Mei sold tickets to closeted men - guarding their secrets and finding her own happiness with the projectionist. But when secrets are unveiled, they set in motion a series of haunting events that propel Old Second and Bao Mei towards an uncertain future in America. Spanning three timelines - post-socialist China, 1980s Chinatown, and contemporary New York - Cinema Love is a tender epic about men and women who find themselves in forbidden and frustrated relationships as they grapple with the past and their unspoken desires. 'I loved it. Cinema Love fizzes with energy. The characters are rich and warm and the prose is perfect. Jiaming Tang is a remarkable new voice' Fiona Mozley, author of Booker-shortlisted Elmet 'A tender and enrapturing feat of storytelling' Vanessa Chan, author of The Storm We Made

Tang J: Cinema Love

Cinema Love

'Not just an extraordinary debut but a future classic' Jessamine Chan

Die drei Freundinnen Bea, Chantal und Zoe arbeiten in einem sterbenden Einkaufzentrum. Sie scheinen eine innige Beziehung zu haben, in der Bea ihre Freundinnen für ihre starken Persönlichkeiten bewundert. Sie selbst bleibt blass und hat sich an gelegentliche Witze und Demütigungen gewöhnt.

Als Bea unerwartet fünf Millionen Euro im Lotto gewinnt, liegt plötzlich der Fokus auf ihr. Die Freundinnen stören sich an der neuen Dynamik und drängen Bea mit diversen Psychospielchen zurück in ihre alte Rolle. Und auch Bea selbst ist mit ihrem neuen Status überfordert. Sie fühlt sich gefangen, obwohl ihr doch jetzt alle Möglichkeiten offenstehen.

So entsteht ein Machtgefüge, in dem Bea schließlich so sehr von Schuldgefühlen erdrückt wird, dass sie Erlösung in Verzicht, Selbstaufopferung und Masochismus sucht. Wird die Freundschaft der drei Frauen diese Krise überstehen?

Bunny war böse

A whimsical queer romance about two mismatched roommates whose fragile—and definitely not romantic at all—balance is upended by an impending family wedding and an otherworldly danger in the nearby enchanted wood. There are at least 100 things wrong with Meredith Schwarzwelder. In fact, keeping track of these things is the only way David Carew has managed to remain living with him for as long as he has. Meredith is an irredeemable eccentric who flirts with everyone in his path (#3 on the list), cries at anything (#35), makes the worst coffee in the world (#70), and talks to mice, or imagines he does (#50). It’s bad enough living with such a person on the edge of the Midnight Wood, but when magic starts to seep from the wood and a dark being emerges with a sinister plan involving Meredith, David decides that it’s time to leave the cottage, and his roommate, behind. Then Meredith’s brother gets engaged to the daughter of David’s boss, and David sees an opportunity: If he can insert himself into the festivities, maybe he can advance his career and get himself out of a personal rut. With wedding bells sounding and the dangers of the Midnight Wood encroaching, David realizes there’s much more hiding beneath the surface of his roommate’s seemingly carefree charm, and that perhaps his own exasperation carries more fondness than he’d like to admit. Cozy, sharp, steamy, and poignant, Into the Midnight Wood is a contemporary queer fairy tale about the masks we wear, the stories we tell, and the powerful need for true, honest connection to heal old wounds and new.

A Memory of Violets

“A tale of rapacious colonialism, Cold War spy games, dazzling technical innovation, big business rivalry, big power geopolitics . . . Niarchos has produced an unflinching, landmark work on the nature of extractive capitalism.” —Patrick Radden Keefe, New York Times best-selling author of Empire of Pain and Say Nothing Epic, shocking, and deeply reported, The Elements of Power tells the story of the war for the global supply of battery metals—essential for the decarbonization of our economies—and the terrible, bloody human cost of this badly misunderstood industry Congo is rich. Swaths of the war-torn African country lack basic infrastructure, and, after many decades of colonial occupation, its people are officially among the poorest in the world. But hidden beneath the soil are vast quantities of cobalt, lithium, copper, tin, tantalum, tungsten, and other treasures. Recently, this veritable periodic table of resources has become extremely valuable because these metals are essential for the global “energy transition”—the plan for wealthy nations to wean themselves off fossil fuels by shifting to sustainable forms of energy, such as solar and wind. The race to electrify the world’s economy has begun, and China has a considerable head start. From Indonesia to South America to Central Africa, Beijing has invested in mines and infrastructure for decades. But the U.S. has begun fighting back with massive investments of its own, as well as sanctions and disruptive tariffs. In this rush for green energy, the world has become utterly reliant on resources unearthed far away and willfully blind to the terrible political, environmental, and social consequences of their extraction. If the Democratic Republic of the Congo possesses such riches, why are its children routinely descending deep into treacherous mines to dig with the most rudimentary of tools, or in some cases their bare hands? Why are Indonesia’s seas and skies being polluted in a rush for battery metals? Why is the Western Sahara, a source for phosphates, still being treated like a colony? Who must pay the price for progress? With unparalleled, original reporting, Nicolas Niarchos reveals how the scramble to control these metals and their production is overturning the world order, just as the global race to drill for oil shaped the twentieth century. Exploring the advent of the lithium-ion battery and tracing the supply chain for its production, Niarchos tells the story both of the people driving these tectonic changes and those whose lives are being upended. He reveals the true, devastating consequences of our best intentions and helps us prepare for an uncertain future. If you have ever used a smartphone or driven an electric vehicle, you are implicated.

A Story of War, Technology, and the Dirtiest Supply Chain on Earth

The Elements of Power

FROM THE AUTHOR OF AS YOUNG AS THIS 'So wryly funny ... Roxy Dunn writes so smoothly about the limitations - and liberations - of adult love with such delicacy and honesty' CLAIRE DAVERLEY, author of Talking at Night 'A thoroughly amusing coming of age (in your thirties) novel written with wit, honesty and tenderness' CLAIRE POWELL, author of At the Table Independence seems to be drifting away from Misty. Just months ago, she was living with her fiancé and planning their life together. Now she's single, back in her childhood bedroom, on crutches from knee surgery, and relying on her mother to help her with the smallest of tasks. This isn't how thirty-two was meant to look. When Misty turns to dating apps, she's immediately intrigued by charismatic, handsome Christopher - so intrigued that she doesn't doesn't even notice the acronym 'ENM' on his profile. By the time she discovers that it stands for 'ethical non-monogamy' - and that he's in a long-term open relationship - she already feels such undeniable, dizzying chemistry that she decides to give things a go. And so Misty makes a pact with herself to date Christopher for the next six weeks while his partner is away. It's all part of her plan: she wants to learn to become less attached, and to prepare herself for her next 'real' relationship. But is what she wants really what she needs? 'So enjoyable ... The writing is just so good and moreish. I loved it' Catherine Airey, author of Confessions 'Roxy Dunn is oh so good on love ... Wants and Needs is witty, warm and seriously sexy' Chloë Ashby, author of Wet Paint

“‘But who are we, if we forget everything that came before?’ Roza wonders in&nbsp;The Jilted Countess. This moving story of one woman finding a new life and new love in the aftermath of WWII answers this question, in the process taking on themes of PTSD, communism, and the plight of being an immigrant in postwar America.”—Meg Waite Clayton, internationally bestselling author of&nbsp;Typewriter BeachIn the aftermath of World War II, a young Hungarian émigré jilted by a G.I. persuades a Midwestern newspaper editor to help her find an American husband in this poignant novel, based on a true story, from the author of The French Winemaker’s Daughter.The war stole Roza Meszaros’s dreams of becoming a ballerina and her aristocratic family’s fortune. But the penniless Hungarian countess’s fate takes a hopeful turn when she meets an American soldier named Joe, who promises to marry her and take her to the States. After two years of waiting to obtain the necessary money and paperwork to emigrate, Roza finally arrives in Minnesota—and discovers Joe has married someone else.Determined to stay in America, Roza turns to popular newspaper columnist Cedric Adams to help her find a suitable husband. Sharing Roza’s story and her picture, Adams makes a special plea to his military readers. The response is overwhelming—nearly 1,800 World War II veterans bombard the paper’s offices with telegrams, flowers, candy, and cash, “a world-record” for marriage proposals, Adams tells Roza.Like a 1948 version of The Bachelorette, Roza ultimately chooses Finn Erickson, a former soldier and railroad locomotive engineer. Putting aside her romantic ideals, she and her new husband settle into the small riverside town of Red Wing, Minnesota. But when Roza unexpectedly runs into her former fiancé, things quickly become complicated.A captivating and unusual tale of love, loss, finding yourself, and creating your destiny, The Jilted Countess examines the meaning of marriage, the American dream, and what it takes to face our demons while searching for happiness.&nbsp;

'A must-read account from a heroic reporter who has taken on the world's most dangerous tech company' - Chris Miller, award-winning author of Chip War: The Fight for the World's Most Critical Technology 'Engaging . . . this excellent book lays out the damage of letting arbitrary political power intervene in business' - Financial Times It's on your phone. It's on your children's phones. It's on more than a billion screens across the planet, serving up joy, creativity and connection. But behind the slick feed of the world's most addictive app lies ruthless ambition and a global war for control. This is the dramatic, untold story of TikTok. Charting its rise from obscurity into the world's most valuable startup, Emily Baker-White reveals how TikTok's visionary founder, ByteDance CEO Zhang Yiming, reshaped the global internet from a place where you searched for information to one where information comes to you. Billions of users were soon hooked by the most effective recommendation algorithm in the world. But there was a cost to such success. Soon, TikTok was embroiled in accusations of surveillance, censorship and user manipulation, attracting controversy from India and Europe to the US. After Baker-White - a Harvard-trained lawyer and investigative reporter - revealed that Chinese engineers could access Americans' private information, a team of ByteDance employees even used the app to track her location. Based on unprecedented access to internal documents, leaked recordings and accounts from whistle-blowers inside the company, Every Screen on the Planet reveals how TikTok became trapped between two superpowers, desperate to survive. It is the story of how your attention became the world's moннннst valuable - and dangerous - commodity. 'Revealing. A story about power, control and the hidden battles shaping what we see online' - Parmy Olson, bestselling author of Supremacy: AI, ChatGPT and the Race That Will Change the World

Weil ihre Freundschaft zu Liebe wird ... Victor 

 Ich soll unsere Ländereinen in Bergbach auskundschaften? Definitiv nicht meine Idee. Aber wenn meine willensstarke Großmutter anruft, hat sie leider immer die besten Argumente. Also tausche ich meinen High-Society-Lifestyle gegen das beschauliche Leben im Wald. Dieser Ort hat zumindest einen Pluspunkt: meinen besten Freund Remo. Doch seitdem ich bei ihm wohne, scheint nichts mehr wie vorher: seine Blicke, seine Stimme, die Art, wie er meinen Namen raunt ...
Um diesen Gefühlen zu entkommen, schmiede ich einen Plan: Ich finde einfach den perfekten Partner für Remo! Überraschend ist nur, dass ich am Ende selbst der Mann an seiner Seite sein möchte.
 Remo

Plötzlich will ich mehr als seine Freundschaft - ich will ihn küssen, will alles von ihm. Doch Victor tritt auf die Bremse und als wäre das nicht herausfordernd genug, kündigt sich auch noch seine Großmutter an, um ihren Enkel zurück in die Stadt zu holen.
