The second book in an exciting new YA/crossover series about genetically engineered individuals with superhuman abilities.

It's hard to remember hating anything as much as I hate Affinity; a bone-deep loathing for the faceless unknown and the concrete walls of my own DNA.

Evie is a Shield: designed to kill in order to protect, and the Affinity Project have finally come for her. But Evie isn't ready for the sinister organisation to take control of her life, her body, her mind. She isn't ready to follow their rules about who can live and who must die - not when it condemns the innocent. She has one option: risk losing everything and everyone - including Jamie - and run.
