In a world where humans have animal companions, one boy must fulfil his hidden destiny. 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. And in a world where the bond between human and animal is the guiding principle to life, this makes him 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.
