The Butterfly Assassin

Available now from Simon & Schuster Children’s Books

The cover of The Butterfly Assassin by Finn Longman. In the centre is a butterfly. One wing is bright yellow, and splattered with paint like graffiti. The other is bright blue. The title is superimposed over the butterfly in white text. Above the butterfly is the tagline, reading "Innocent by day, killer by night", and above that is a quote from Chelsea Pitcher, author of This Lie Will Kill You, reading "An electrifying debut!". The author's name is at the bottom. The cover is black, with grey graffiti-like squiggles creating texture.

Innocent by day, killer by night: a dark, twisting thriller about a teen assassin’s attempt to live a normal life.
 
Trained and traumatised by a secret assassin programme for minors, Isabel Ryans wants nothing more than to be a normal civilian. After running away from home, she has a new name, a new life, and a new friend, Emma, and for the first time in Isabel’s life, things are looking up.
 
But old habits die hard, and it’s not long until she blows her cover, drawing the attention of the guilds – the two rival 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.
