'A dark, enthralling thriller' The Guardian

Teen assassin Isabel Ryans now works for Comma, and she’s good at it: the Moth is the guild’s most notorious killer, infamous throughout the city of Espera. But Isabel still craves normality, and she won’t find it inside the guild. She moves in with a civilian flatmate, Laura, and begins living a double life, one where she gets to pretend she’s free.

But when Isabel’s day job tangles her up with an anti-guild abolitionist movement, it becomes harder to keep her two lives separate. Forced to choose between her loyalty to her friends and her loyalty to Comma, she finds herself with enemies on all sides, particularly those from the rival guild Hummingbird, putting herself and Laura at risk.

Can Isabel ever truly be safe in a city ruled by killers?

From award-winning author Finn Longman, an exhilarating voice in YA fiction, comes an addictive trilogy for fans of global phenomena The Girl with the Dragon Tattoo, Killing Eve and The Hunger Games.
