Unlock the Dark

"Elia Tallis's key conjuring abilities, when used with her father's magic, allow her to open a path to any location. But Papa is dying, and Elia has been forced to painfully tether him to life so she can siphon his magic to provide for her siblings. The god of death, angry to be denied his due, punishes her by claiming her youngest brother as a servant. Desperate to save her brother, Elia accepts a potentially deadly commission from Trys, a kindhearted prince with his nose stuck in a book. Trys wants Elia to help him find a legendary scroll. In exchange, he'll give her his hand in marriage, securing her and her siblings' futures and allowing her to release Papa to the afterlife"--
