In their world, humans regenerate, heal, and live for hundreds of years. Mortality isn't something to fear. Disease has been all but eradicated. Everything changes when Ava watches her brother die and he doesn't regenerate. Ava's genetics are called into question by the government, scientists, extremists, and Ava herself. Could her genes hold the answer to mortality? Is she an anomaly or something to be feared? Determined not to become anyone's guinea pig, Ava doesn't stick around to find out.

If either of them have even the slightest chance ofsurvival, they must find the genetic keys hidden in Ava's DNA before it's too late."--Back cover.
