Saint's Temptation — Debra Dier

A man hardened by war must fight to resist the temptation of the only woman he has ever loved, the one woman who broke his heart.

After his young love Marisa Grantham ended their engagement, Clayton Trevelyan, Earl of Huntingdon, had no intention of letting another woman close to his heart again. Seven years later, the army had hardened him from the shy scholar he once was, and he knew just what he needed in a bride: She must be quiet, dignified, intelligent, and above all, have no illusions of marrying for affection. Allowing himself to taste the forbidden fruit of Marisa's desire had proved much too dangerous.

When Marisa overheard two men discussing plans to murder Clayton, she swore she would do anything to keep the stubborn earl alive. She was no longer the naive young woman who had allowed her one and only love to walk away; she would not lose him a second time. But when breaking through his heart's defenses proved as difficult as outsmarting a murderer, Marisa knew she would have to use all her feminine wiles to tempt a saint.
