Too stubborn not to butt heads…too attracted to each other not to fall into bed.

Dexter “Dex” Wright is never wrong. It’s not an ego thing, it’s a fact reflected by a drawer full of military medals and commendations. He’s great at protecting people, and even better at guarding his heart—skills honed by a stint in Delta Force and from growing up in the system. But daily contact with the beautiful, stubborn sister of one of his military buddies is slowly thawing the unreachable.

Rylee Bryson grew up a military brat. Instead of rebelling against the regimented, disciplined lifestyle, she embraced it. Too bad her family wants her to get married and play it safe behind a desk. She tried that—even got engaged—but neither worked out. So when she learns her brother’s buddies need a receptionist for their security and investigation company she jumps at the chance—not to trade one desk for another—no, Rylee is on a mission to prove she has what it takes to be an agent. If only she didn’t have to work with the sexy jerk who broke up her engagement.

With the tempting woman assigned to work undercover with him on a case, Dex can’t seem to keep his hands or his mouth off his partner. But more than his heart is at stake if he doesn’t keep his head in the game.
