HOT SEAL by Lynn Raye Harris

An enemies to lovers, ex-spouses forced to work together, second chance, Navy SEAL romance from New York Times Bestselling Author Lynn Raye Harris.

When a terrorist steals a drug submarine, Navy SEAL Dane “Viking” Erikson finds himself thrust into a mission with an unexpected partner. His ex-wife, Ivy McGill. Dane would rather be staked to an ant hill naked than work with Ivy, but refusing a direct order from his new commanding officer isn’t healthy for his career.
DEA Agent Ivy’s on a mission of her own to put a ruthless drug dealer out of business for good before he causes another little girl to experience the heartache she once did. If she has to work with the man who shattered her belief in love to get the job done, so be it. She’ll survive being forced to work with the sexy SEAL because there’s no way she’ll fall for his swagger again.
But infiltrating an enemy operation means going undercover together. Faking a relationship. Sharing a room. Shouldn’t be a problem since they hate each other, right? They’ll do the job and go back to forgetting the other exists.

Except working together forces them to admit something neither of them thought possible. They aren’t done yet. They might never be done. But if they’re going to figure it out, they need to survive the mission. Then maybe they’ll get a second chance to make things right.
