Ely and Jake Anselm aren't exactly brothers. In the near future, when laboratories churn out everything from babies to pancreases at the convenience of those who can afford it, few accidents are without remedy. Still, no world is error-free--which is how Jake ended up with a clone instead of a new kidney. Bound by shared blood and scars, the Anselm boys have cultivated a peculiar habit of sameness that grows strained by their impending high school graduation. Only their best friend Marco Sepúlveda--part emotional support dog, part principal investigator--seems to understand. As his connection to Jake splinters, Ely finds himself drawn to his classmate and onetime hookup, Vera Zhao, though her identity crisis might be even worse than his. For the four of them, determining the future depends on uncoiling the past. Is identity something you're born with, or something you're born to lose?
