A pirate's possession (Berkley Sensation mass-market ed.)

Pleasure won is more precious than treasure found in this scintillating pirate romance from Michelle Beattie.

Abandoned by her father and married to a deceitful man, Claire Gentry fled from her life. Now, disguised as a man, Claire wagers all she owns in a poker game to locate the treasure her father sought. But while her disguise holds, it doesn't protect her when one of her opponents turns out to be the man she once gave her heart to.
 
Sailing under the alias of the mysterious pirate Sam Steele, Nate Carter is looking to gamble for a map that will lead him to a treasure. But when he looks over his cards and sees Claire, he's reminded of a past he'd rather forget-and of the woman who could have given him everything he truly wanted.
 
When Nate wins the map, Claire has no choice but to accompany her old love on his quest. And if they survive the bloody battle for the treasure, they may just realize that what they've really been searching for isn't riches-but each other...
