Hot SEAL, Under Pressure by Cat Johnson

He thought he knew pressure, until he was coerced into doing a reality show that pairs Navy SEALs with civilians in a no-hold-barred contest for a huge cash prize.
But more than the prize money. His honor is on the line. He’ll be damned if he’ll be bested by the competition, even if the sexy female civilian he’s been paired with is hopeless at shooting, and sky diving, and fast roping, and the obstacle course. And even if there’s no chance in hell he’ll be able to make it to the end without giving in to his attraction to her.
There’s entirely too much touching. Too close quarters. And she looks way too good when she’s failing so spectacularly at the challenges.
It’s almost enough to make him not care about losing the game, as long as he can have her.
