Marked By the Bobcat by Zoey Indiana

Dawson signed his life away… Until Xia shattered his reality.

Dawson, a bobcat shifter, never expected to find love. Convicted of a crime he didn’t commit, he signed up for an experimental military trial that gave him fledgling wizard powers. But when he discovers his fated mate, Xia, moments before being abducted by the same enemy who ruined his life, he’ll stop at nothing to save her.
Xia, a flying fox shifter, lost her arranged mate to the enemy who now has her in his clutches. With her life in shambles, the last thing she expects is to find her fated mate, Dawson, who swoops in to save her. But she’s not sure she can trust him, and her son hates him on sight.
As Dawson and Xia navigate their tumultuous relationship, they must also face the enemy who threatens their very existence. Dawson’s powers make him the perfect spy, but he must decide whether to continue following orders or follow his heart and protect Xia at all costs.

With danger lurking at every turn, Dawson and Xia’s love is put to the ultimate test. Will they be able to overcome the obstacles in their way, or will their love be the one thing that destroys them both?
