BloodWind by Charlotte Boyett-Compo

"As a member of the Resistance, Dr. Bridget Dunne's assignment is to tame the Prince Reaper Kamerone Cree. Though she fears the Shapeshifter, she knows the only way her fellow captives will ever know freedom is to bring the Iceman Cree over to their side.

Athough totally dedicated to upholding the ideals of the brutal Rysalian Empire and crushing the Resistance, Cree instead is forced to regain his humanity. When he finally claims Bridget as his woman, he has to overturn worlds in order to keep her."
