The epic conclusion to the dark, twisting thriller trilogy about a teen assassin's attempt to live a normal life.

'An immersive, fast-paced thriller' The Irish Times

Isabel Ryans has fled Espera, leaving behind her identity as teen assassin the Moth. Now she's trying to adjust to the reality of the outside world. But her grief and trauma are catching up with her, and surrounded by civilians who will never understand what life is like in the walled city, she feels more alone than ever.

When a journalist is murdered nearby, suspicion automatically falls on Isabel. And inside Espera's walls, the abolitionist movement is gaining strength. When Isabel's search for the killer leads to an unexpected reunion, she's forced to decide whether she can really leave the city behind, and what part the Moth might have to play in the uprising.

Is Isabel Ryans the city's saviour . . . or its scapegoat?

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.
