Kayel, Sahri, Kir and Grayson all live in a society where people are ranked into castes. Kir lives at the top with her rich family, where Sahri has been placed in a low one and plays the roll of servent to Kir's family. Kayel is much more of a free spirit, not allowing the castes to limit him. Grayson is without a caste and lives on the side lines. What do these four have in common? They're all Beast-Kin, humans with spirit animals giving them all supernatural abilities. But these Beast-Kin are fed up, and no longer want to live in fear because of who they are, and they will do what it takes to keep them alive.
