Her Guardian Wolf (Sawtooth Shifters, Book #2) by Kristen Strassel

Kiera grew up in a man’s world and has the scars to prove it. First as the only girl in a family full of brothers, and then in the Army’s EOD unit. She’s working at Forever Home animal shelter as rehabilitation for her PTSD, and these animals are about to change her life. But it’s a rescued werewolf that sees her in a way no one else ever has.

All Baron Channing knows is war. His family has protected Sawtooth Forest for generations, but now a rival pack has them at their mercy. They’ve got Keira in their crosshairs, and Baron’s been assigned to guard the women who saved him and his brothers from a fighting ring.

Baron’s tired of violence, and if his pack will survive this attack, they’ll have to fight harder than they ever have before. He’ll do whatever it takes to keep the incredible woman he’s been assigned to protect safe and make her his mate.
