In the aftermath of the animal kingdom rebellion, mankind teeters on the brink of extinction, with only Will-C, Yoshi and a ragtag network of domesticated animals, ready to help protect the scattered survivors from the roaming hordes of deadly predators. Meanwhile, Drue and the Nsray shape-shifters discover that their only chance to bring an end to the worldwide conflict lies with BlækLight, a mysterious extraterrestial life-force buried deep in a frozen cave beneath the Amazon rainforest. Its exact location is known only to the Lloque, a fearsome indigenous tribe previously unknown to man, who have guarded the secret for centuries and are ready to lay down their lives in order to protect it.
