Books like Night Thunder's Bride by Karen Kay

His Wife in Every Way He had promised to protect the beatiful white woman. But a Blackfoot warrior must never raise a hand against his own brothers, even if they mean to harm and disgrace a helpless captive. There was only one thing a man of honor like Night Thunder could do: claim Rebecca Cothern as his wife. But One. From the moment Rebecca stepped into Night Thunder's powerful embrace in full view of his tribe--making his marriage vow true in their eyes--she knew her life would never be the same. How could she travel among his people as his "wife" and share his bed without succumbing to the desire that burned so fiercely in her breast? Night Thunder swore that she would truly be his bride in every way, if only Rebecca would give hreself to him freely and without remorse. But could she sacrifice the only life she's ever known--and the future she'd always dreamed of--for a deep, satisfying tast of forbidden passion?
