Generations trilogy

"Waking up in a mysterious enclosed space with no memory of their identities, a group of adults uncovers evidence of a long-past war and the horrifying realities of their confinement"--OCLC.

At last, our heroes, Alive and Alight, get to the bottom of the confounding mystery of their own existence. At the same time, they must contend with the fact that if they can't defend the planet their bodies were engineered to inhabit, they'll be forced to flee--in hopes that some corner of the far-flung universe will prove hospitable.

After waking up in a strange enclosure, a group of teens sets out to escape their captivity and discover the truth about their identities.

"The planet Omeyocan may be the sanctuary Em and her comrades seek. But the planet for which they were created turns out not to be a pristine, virgin world. Vestiges of a lost civilization testify to a horrifying past that may yet repeat itself. And when a new enemy creeps from the jungle shadows, Em and her young refugees learn there's nowhere left to run. They face a simple choice: fight or die"--Amazon.com.
