“If I touch any more of you, I won’t be able to stop.” Software engineer Cooper Hale lives and dies by the KISS Principle—Keep It Simple, Stupid. It’s made his start-up a huge success. If only he could find a way to simplify his love life. His neighbor Allie is the sexiest woman he’s ever met and her apartment is only a floor away. The proximity screams simple. Everything else about Allie—her confidence, her brain, even her shoes, says he could be getting in over his head. With an ad agency to run and her ex interfering, Allie Flynn has had her quota of complicated. So why does she keep flirting with Cooper in 3B? He’s everything she shouldn’t want—still in his 20s, whip-smart, and too hot for his own good. She needs Cooper as a friend. Her heart can't take another guy who's passing by, but can the rest of her handle it when he goes in for a kiss? The KISS Principle is a stand-alone erotic romance with a happily-ever-after. It is intended for readers 18+. Originally published under the title For Keeps, the 2015 re-release has an all-new cover and new, low price.
