Blood on her hands. No one really understands Mary Costner, except her beloved gold-mining partner, one of the only men in Colorado's Gregory Gulch who knows she is a woman--and who treats her like his daughter. But when Mary wakes up one night covered in blood--with no memory of why her partner is dead--she knows she looks guilty as sin. So she does the only thing she can. She runs . . .Desire in Her Heart. Fleeing in a raging blizzard, Mary is thrown from her horse and knocked unconscious. She is found by tough-as-nails U.S. Marshal Carter Monroe, whose gut tells him that this bedraggled blonde must be trying to escape from something or someone. When Mary finds herself in the home of a marshal, she can't believe her luck. She'll have to keep a tight rein on her secrets to keep Carter off guard--even as her body's hunger for the lawman's touch threatens to betray her.
