Underworld meets cowboys in the Montana mountains in this thrilling, sexy paranormal romance from beloved author Kait Ballenger!

Grey Wolf high commander Colt Cavanaugh has spent his life defending his pack from attacks. With sprawling ranchlands extending well into the mountains, it's a good thing he's also a hardened cowboy who's not afraid to get down and dirty. But Colt has a dark secret that could destroy his life if he's not careful, and she goes by the name Belle Beaumont…

Belle promised Colt that their one-night tryst was just that―that no one would ever find out the sworn enemies had shared a passionate night together. But now Belle is a wanted woman, on the run from the wolf pack that kidnapped her, and she's desperate enough to do just about anything to stay alive. When fate brings her back to Colt, rivalry becomes passion, and suddenly more than just her freedom is at stake.

Colt will fight to the death for the healing Belle brings to his battle-worn heart―and for this cowboy wolf, all's fair in love and war…
