Devil’s Tango by Claire J Monroe

Captain Donovan “Van” Tatum is a black ops soldier in a secret organization that deals in all things paranormal and exists for one reason: To protect the Republic. He didn’t have a problem doing his duty until he fell in love with a job, then married her. But all’s fair in love and war and, when an enemy of the State started targeting and killing mates of the men in the organization, he had no choice but to cut himself out of his mate’s life and leave with no explanation. Making that sacrifice nearly destroyed him, but it’d worked.

Until now.
Maddie Colby Tatum isn’t stupid. Five years ago, Van left her for a reason and until she knows what it is, she’s not moving on. Not even when he shows up in her living room and tells her to run with him because there is a hit team crawling up her lawn hell bent on collecting the bounty on her head. Okay, fine, she’ll run. This time. But let him back into her life in that permanent-sexy-man-growly way he keeps saying is gonna happen…?

Maddie: Uh-uh. No way. Not happening. Not until he opens up and starts giving her the truth. And even then, it’s not happening. At all. Ever.
Van: Oh, it’ll happen. Of that he has no doubt. But whether he survives her anger once she’s got her answers…? Maybe. If he’s very, very lucky.
