Confused, hurt, and alone, he must survive long enough to be rescued by his friends, who embark on a dangerous quest to find the antidote.
However, time is running out, and Onyx's mind is slipping away. Hydra teams up with Lilith to uncover the hidden secret behind ephages, a viral technology that is their only hope. A daring journey into the heart of the old world ruined by nuclear apocalypse brings her face to face with the world's most dangerous creatures.

He is introduced as the bachelor of honor at the Debutante Gala, a sophisticated high-class event where he meets the lovely Pyrexia Ophrys.
The story culminates in an epic showdown at the zoo where friends, enemies, and lovers meet to admire the exhibits, and compete with each other for the spoils of romance. Will Thermos choose Hydra, the girl who broke his heart, or Pyra, his steamy new flame?
