More than three hundred years after the most terrifying witch hunts the world has ever known, it's happening again. When an attack by ruthless witch hunters forces twenty-four-year-old Stella from her home in London into the protection of the powerful Witch Council in New York, she has to put her faith in strangers just to stay alive, yet she might not be any safer in their midst than the danger she escaped.

Hidden from the Brotherhood in an extraordinary safe house by the sea where she is sent to learn her craft, Stella finds there is more than one dark secret in her new family: Etoile's sister is spoken of in fear and sadness; Marc is supposed to be a powerful warlock but is missing his magic; where does the owner of their safe house vanish to every day and why does Evan have the eyes of someone not quite human?

One secret is important enough to kill for and it's a secret so powerful it could destroy the fragile threads of Stella's new world.
