Rival. Enemy. Teammate. Friend. Lover.

The first time NFL quarterback Heath Harris meets Sam Crawford, it's just them, a luxury yacht and a few days of fun in the sun. Sam turns out to be nothing like Heath expects. He's kind and funny and irreverent-and also unbelievably, shockingly sexy. For three short, glorious, life-changing days, there are no rules.

The second time they meet, Sam has just been traded to Heath's team, and instead of lovers, they're now rivals. Heath has spent the last five years working desperately to be the best quarterback the Riptide could ever need, but when injuries threaten to derail his career, Sam is right there, standing on the sideline. Ready to take over, and ready to ruin everything Heath has given his life for.

Rival. Enemy. Teammate. Friend. Lover.

As their orbits collide, sparks fly, and Heath struggles to find the right label and the right box to shove Sam into, hoping to keep him contained. But Sam-and Heath's feelings-refuse to cooperate.

Sam might not be just one of those things, he might be all of them, and so much more.
