Genevieve is the only sidhe fae in London and has a traumatic past involving vampires, which we readers learn about in flashbacks throughout the story. She works as a spellcracker, removing hexes from objects. There are two ways she can remove a spell. She can “crack” the spell, thereby destroying both the spell and the object, or she can absorb it into herself, which carries its own problems. As the story begins, a celebrity vampire stands accused of murdering his girlfriend, Melissa. The vampire’s father hires Genny to examine Melissa’s body for evidence of magic.
