Lexa, Gabe, and Nathaniel discover new abilities, learn each other's secrets, and find out just how far they'll go to save their friends' lives. Lexa and Gabe take comfort in their new relationship, though Nathaniel hasn't given up winning Lexa for himself. Even with two alpha-males and her own kick-ass attitude for protection, Lexa's abducted by genocidal aliens for her hybrid DNA. Gabe and Nathaniel attempt a rescue, only to find they're trapped on a deadly spaceship. They have to escape before the ship takes off, or they're screwed and humanity's left targeted for extermination. They're certain it's as bad as it can get. It's not.
