Hook, Lyon and Sinker by Jude Knight

When Laurel jilts her fiancé will it bring her scandal? Or everything she has ever wanted?
When Lady Laureline Barker asks Mrs. Dove Lyons to find her a husband, she does not expect one of her choices to be the man she admired years ago, when she was still a schoolgirl—the man who rescued her from drowning. He is also a war hero, famed for trading his own freedom and health for the safety of others.

Laurel is committed to a contest, with the winner taking her and her dowry. Can she back out? And will he still want her if she does?

Angelico Warrington doesn’t expect Laurel to remember him. Even if she does, why should she favor him over other suitors? She is the respected sister to an earl, with only one flaw on her reputation—she refused to marry a cad who had been putting off their wedding date for five years.
