No Other Man by Heather Graham

Comanche Moon meets Savage Thunder in this sweeping Western Historical Romance of betrayal, desire, and redemption on the untamed frontier.

Lady Skylar Douglas thought she’d married a dying British lord to secure her future—but when her stagecoach is ambushed in the heart of Sioux Territory, she’s torn from everything she knows and thrust into the arms of a man she can’t trust… and can’t resist.
Hawk is no ordinary warrior. A proud Sioux, a former Union officer, and the real Lord Douglas, he’s enraged to discover the woman claiming his title—and even more incensed by her fiery spirit and haunting beauty. Skylar may be a con artist… or she may be the one person who can expose the truth behind his father’s death.
As passion ignites between them and danger closes in, Skylar and Hawk must decide: will they destroy each other—or save themselves?

In a land ruled by bullets and betrayal, can love survive when it begins with a lie?
