Cynthia Hobbs is in trouble. Considered spoiled and vain by the townsfolk of Brimstone, she's hiding a secret—a sister who needs constant care. When her father informs Cynthia that she has to marry the slimy vice president of the bank—and her sister is part of the deal—Cynthia grows desperate. The only person who'll help her get enough money to escape town with her sister is the madam of the Jeweled Ladies—who recommends Cynthia sell her virginity to the highest bidder. 

One night will solve her problems—if she can go through with it.

Cam Douglas wants to go straight—there's a horse ranch waiting for him. But he needs cash, so he takes one last job—this time, robbing the bank in Brimstone. He visits the Jeweled Ladies for an alibi but somehow winds up buying a virgin at an auction, which is a great alibi. He has no intention of forcing the girl, but when Miss Diamond insists on being deflowered, he's far too much of a gentleman to say no to a lady. 

Cynthia never dreamed she'd enjoy this night, but Cam is a rogue with a heart of gold. He gives her a night of steamy memories and then they part ways. But as she and her sister make their escape from Brimstone under cover of darkness, a rider takes them by surprise. It's Cam, with a gunshot in his shoulder and a posse on his tail. If she protects him, they all might be caught. But she likes him, much more than she should. Can she risk her heart—and her sister's safety—for a rogue?
