Under The Surface by Kira Sinclair

Lusting after the enemy.

Former SEAL Jackson Duchane has spent almost a decade hunting down the wreck of the Chimera, a Civil War-era ship rumoured to be filled with gold. Now he's agonisingly close to the biggest discovery of his life. With a rival diving team hot on his trail, Jackson is determined to get there first but he didn't bargain on a sexy distraction…

Heading up a diving team is Loralei Lancaster's nautical nightmare. Fortunately, nothing distracts a girl from her water phobia like a gloriously ripped surf god. Jackson is hot enough to make Loralei forget everything — including the fact that he's an arrogant jerk! And when heated words lead to steamy nights, Loralei finds herself caught between the devil and the deep blue sea!
