When Bailey enters the prestigious Fairmount Academy as a freshman, he is the only member of his class who doesn't yet have an Animas. In a world where the bond between human and animal is the guiding principle to life and emerges naturally during puberty, Bailey feels like an outsider both at school and in the world at large. But Bailey is more important than he knows. He is the key to an ancient prophecy that will restore the rightful heir to the throne of a kingdom ripping at the seams. Through his budding friendships with Hal, Tori, and Phi, along with the unlikely help of renegade teacher and former conspiracy theorist Tremelo, Bailey must learn to find his Animas, piece together the riddle of the prophecy and start on the path that will lead them all to their destinies.
