Siray is young, beautiful and idealistic. She is prepared to take on the responsibilities - and amazing abilities - of an adult Kaslonian. Once she goes through the Change ceremony, she'll have everything she wants...won't she? Siray is about to experience the most important moment of her life, the Change ceremony, where she will transform into her chosen animal form and take her place in society. It is all she has ever wanted - to live a normal life amongst her people. But when she is forced into an emerging war, she finds that sometimes, destiny is its own master.

And now that Siray can Change into an animal form, the rare and revered sevonix, the Faction will stop at nothing to capture her. As she flees with her friends, Siray must hide her true gifts from the rest of the world; a task made more dangerous as she faces trial and hardship, battles enemies, make new allies and face even bigger threats...

Yet the mysterious, commanding figure that has haunted her dreams is watching closely, and Siray soon finds her future forever altered as her real enemy finally reveals himself and his plans. She must survive. So she will Change. And become something new…
