Always to Remember by Lorraine Heath (1996)

HISTORICAL: Post Civil War Romance
HEROINE: 23 year old widow

Refusing to pick up a gun for the Confederacy, Clayton Holland was branded a deserter and imprisoned during the war. When he returned home to Cedar Grove, he was given a coward's welcome, spurned by everyone in town. To Meg Warner, Clay's presence was a constant offense: a betrayal of the cause for which her husband and brothers died.

As a punishment, she commissioned Clay, a talented sculptor, to create a memorial for Cedar Grove's fallen heroes, hoping that every name he carved into stone would carve remorse into his heart. But, as Meg spent months watching Clay work, she began to see strength instead of cowardice. And she discovered that a hero could be found in the most unlikely of men. That passion could be sculpted from a heart hardened by bitterness. And that sometimes love―like courage―whispers instead of shouts.

Once a Pirate by Susan Grant (2000)

HISTORICAL: Pirate Romance
TIME TRAVEL: Modern day to past
SETTING: Atlantic Ocean 1821
HEROINE: 27 year old Navy pilot from USA who travels back in time

Andrew Spencer sailed the seas seeking revenge, and there were very few merchants' treasures that he hadn't given a jolly rogering. But on this particular voyage, he found his task harder than usual. As a brown-eyed beauty was hoisted from the waves, he found his pirate's soul plundered from without and a fiery need conjured up from within.

The freak storm that caused her plane to go down in the Atlantic sent fighter pilot Carly Callahan's life spinning out of control as well. Pulled from the freezing ocean, she found herself in the hot embrace of an Adonis. But his eyes were cold and hard, and the man's burning lips swore she was someone else before he claimed her as his own. Carly knew she had one chance to go home, but there was so much to see and feel here -- and the best was yet to come.

The search for it will pull the Frasers into a maze of intrigue that winds through the lowest and highest levels of London secrets -- revealing layer upon layer of deception and betrayal, and a shocking truth that binds Charles and Mélanie inextricably together ... even as it threatens to destroy them both.
