The Butterfly Assassin

May 2022 – Simon & Schuster Children’s Books

A dark, twisting thriller about a teen assassin’s attempt to live a normal life.
Trained and traumatised by a secret assassin program for minors, Isabel Ryans wants nothing more than a new life as a normal civilian. And she might just be in with a shot when she befriends Emma Westray, because for the first time in her life things are looking up.
But when Isabel blows her cover by impulsively murdering a burglar, she draws the attention of the guilds – the two organisations who control the city of Espera. An unaffiliated killer like Isabel is either a potential asset … or a threat to be eliminated.
Will the blood on her hands cost her everything?

From Finn Longman, an exhilarating new voice in YA fiction, comes a blockbuster new series for fans of global phenomena The Girl with the Dragon Tattoo, Killing Eve and The Hunger Games.
