Betting the Scot by Jennifer Trethewey

Declan Sinclair is a Highlander who believes his dreams never lie. When he spots Caya at a public house, he knows instantly she is the woman in his dreams—his future wife. Though her brother had promised never to gamble again, he engages Declan in a card game—and the prize is the lovely Caya.
Caya Pendarvis has no time for childish things like dreams or fairy-tales or love. She’s the sacrificial lamb on her way to the far north of Scotland to wed a wealthy merchant in exchange for settling her brother’s gambling debts.

Winning at cards is one of the many things Declan Sinclair does well. Unfortunately, the ability to court a woman—a talent he lacks—is the only skill he desperately needs to win Caya’s heart.
