The Horse Mistress, book 1R.A. Steffan2015

Carivel was born female, but she has been secretly living as a boy for years in her adoptive village of Draebard. The last thing she needs is to fall for not one, but two unattainable men—a fierce warrior and a reluctant wolf-shifter with a horrific past. Now, the Alyrion Empire is poised to invade, and Carivel must choose whether to keep her secret or reveal it—not only to the men she loves, but also to the powerful female ruler whose army could help protect Draebard during the coming war.
