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. 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?
