The Wager — Robin Lee Hatcher

Beautiful, sheltered and flirtatious, Bethany Silverton just couldn't resist the challenge of charming the most unregenerate cowboy in town into attending her father's new church. But when she made her innocent wager, Bethany never dreamed that she would be the one charmed by Hawk Chandler's dark good looks, seduced by his hard masculinity, swept away in a wild night of unforgivable sin and unforgettable pleasure. Before she knew it, her reputation was in shreds, and she found herself the unwilling bride in a shotgun wedding. Hawk was the last man she'd ever expected to marry, yet he would be the first one to bring her to the soaring heights of love.
