Comanche Passion — Sara Orwig

THEY WERE STRANGERS...
Traveling to Texas to help her sister escape an abusive marriage, Savannah Ravenwood is seized by a powerful dark-haired stranger. Her captor is Red Hawk, a half-breed Comanche who needs a woman's help in rescuing his orphaned nephew. Red Hawk sweeps Savannah into a passion as stormy as the conflict that rages on the Texas frontier.
...DRAWN TOGETHER BY FIERCE DESIRE
Though this proud Comanche shares her determination to rescue a loved one, Savannah must resist the intoxicating attraction she feels for him. For surrendering her heart to a man whose only desire is to return to his Comanche people means abandoning all she knows and holds dear. Now, not even their growing love can bridge the gap between their two worlds-until tragedy reveals the only future worth fighting for is a future together.
