A forgery of roses
(Book)

"She's a portrait artist whose paintings alter people's bodies, which is a talent some would kidnap, blackmail, and worse to control. Guarding that secret is the only way to keep her younger sister safe now that their parents are gone. But one frigid night, the governor's wife discovers the truth and threatens to expose Myra is she does not complete a special portrait that would resurrect the governor's dead son. Once she arrives at the legendary stone mansion, however, it becomes clear that the boy's death was no accident. A killer stalks these halls -- one disturbingly obsessed obsessed with portrait magic. Desperate to get out of the manor as quickly as possible, Myra turns to the governor's older son for help completing the painting before the secret she spent her life concealing makes her the killer's next victim." --,(Source of summary not specified)
