Wes Sinclair is a notorious heart-breaker, a hot-as-sin bad boy with a panty-dropping smile no woman can resist. Except for his best friend’s little sister and his business adversary, Natalie Prescott, who seems immune to his flirtatious charms. While she’s become a permanent fixture in his dirtiest, most scandalous fantasies, she wants nothing to do with him or his seductive promises. Challenge accepted. His goal? To bring her to her knees, make her beg, and show her just how good being bad can be.
