The Dragons of Winter — P.A. Brown

Ciburon is poised to bond with Alecca, his predestined mate and ascend as sovereign crown of Xyamaira. But he has rivals who seek to supplant his rule. If they can prevent Ciburon from successfully teaching Alecca in the ways of his people, the dragonshifters, and mate according to custom, he will forfeit his kingdom and face exile or death.

Kytam, a powerful white dragonshifter mated to blue Tamhrin seeks to prevent Ciburon's success by any means necessary, including trickery and betrayal.
