No one saw it coming. The attacks began out of nowhere. Giant alligators emerged from the sewers, huge bats swarmed New Mexico, an army of Chupacabras invaded Texas, and Thunderbirds soared the skies searching for prey. . .

Humanity's only hope is to find out what is behind the attacks and destroy it or face extinction!
