A terrifying prophesy. An undying love. The ultimate sacrifice. Maximum Ride is used to surviving - living constantly under threat from evil forces sabotaging her quest to save the world - but nothing has ever come as close to destroying her as the horrifying prophesy that Fang will be the first to die. Fang is Max's best friend, her soulmate, her partner in leadership of her flock of bird kids. A life without him is a life unimaginable. Max's desperate desire to protect Fang brings the two closer together than ever. But when a newly created winged boy, the magnificent Dylan, is introduced into the flock, their world is upended yet again. Raised in a lab like the others, Dylan exists for only one reason: he was designed to be Max's perfect other half. Thus unfolds a battle of science against soul, perfection versus passion, that terrifies, twists, and turns ...and meanwhile, the apocalypse is coming.
