The fourth book in M.L.N. Hanover’s acclaimed Black Sun’s Daughter series featuring “smooth prose and zippy action sequences” (Publishers Weekly).

Jayné Heller has discovered the source of her uncanny powers: something else is living inside her body. She’s possessed. Of all her companions, she can only bring herself to confide in Ex, the former priest. They seek help from his old teacher, hoping to cleanse Jayné before the parasite in her becomes too powerful. Ex’s history and a new enemy combine to leave Jayné alone and on the run. Her friends try to hunt her down, unaware of the danger they’re putting her in. Jayné must defeat the past, and her only allies are a rogue vampire she once helped free—and the nameless thing hiding inside her skin.
