1930s haunted York. Viola Samphire was part of a coven of four powerful witches, but now only three survive. A devastating fire in an artist's studio led to Edie dying of smoke inhalation. When Viola discovers that the fire was no accident, she hunts for clues, but something has changed within her - she can she ghosts wherever she goes, both friendly and menacing, and more importantly, she can see the ghost of Edie, the witch who died in the fire, and her unrequited love.
