The Gunfighter and the Heiress — Carol Finch

From hired gun to hired groom

Money can't buy love...but it can buy marriage for on-the-run shipping heiress Natalie Blair. Her vicious stepfather's scheming ways have the Louisiana beauty fleeing to Texas to seek out legendary contract gunfighter Donovan Crow. He is dark, dangerous, and marrying him would be the perfect protection...

For Van, the price is right and the spirited woman is impossible to resist. Soon the hardened bachelor can't tell what's more challenging -- keeping their legions of enemies at bay or keeping his hands off his fake wife!
