Laws Of Attraction (Marriage & Mayhem! #1)
Diana Duncan

They're a perfect pair, both tough, wary, and the walking wounded. When their quests for vengeance collide, Undercover DEA Agent Dallas McQuade and Mia Linden, a disbarred lawyer whose personal life has been destroyed by drug lord Esteban Montoya, are forced into a reluctant partnership—and a quickie Las Vegas wedding.
Dallas vows to protect his temporary wife, but Mia has plans of her own, and they don't include leaving all the heavy lifting—or bullet-dodging—to Dallas.
Neither of them planned on falling in lust, let alone love. But they can’t fight the passion…and emotions…ricocheting between them.
Maybe they can heal each other. And their make-believe marriage can become real.
If they survive.
