Fang is Max's best friend, her soulmate, her partner in leadership of her flock of winged children.

A life without Fang is a life unimaginable. Max's desperate desire to protect Fang brings the two closer than ever. But their world is turned upside down yet again when the Flock meet a wealthy scientist who has a great interest in the birdkids.

He introduces them to another winged boy, the beautiful Dylan. Raised in a lab like the Flock, he exists for only one reason: he was created to be Max's perfect other half. Now, a battle of science against soul, perfection versus passion unfolds, twists, and turns ...and meanwhile, the apocalypse is coming.
