Zeph is a gryphon who wants nothing more than to spend his days happily hunting parrots in the untamed forests with the rest of his pride, but after a wild chase gets out of hand, he stumbles upon a blood-soaked notebook full of secrets. The sort of secrets his brethren in the eyrie above would kill to keep hidden. The opinicus Kia, an evolved relative of a gryphon, wants nothing more than to hide in her sky-city and study ancient tomes. But when her scholarly friend goes missing, she’s sent to the gryphon lands to investigate. She doesn’t think things can get any worse than having to team up with a gryphon named Zeph, but what they uncover will put both their worlds in grave danger. Can gryphons and opinici work together to stop their worlds from burning down, or has the fuse already run out?
