"I dare you…" Riley Kendrick has officially lost her nerve. Since being robbed last year, her spontaneous side—the fun side—has been completely MIA. That is, until her new neighbor moves in. Jack Reed, aka Mr. Apartment 4B, is over six feet of hard, sculpted hotness with a dimpled smile…one that suggests that maybe it's time for Riley to get in touch with her once-naughty self. Now the dares have begun. What started in an elevator has quickly escalated to a game of sexy challenges, each more daring than the last. It's exciting, it's wicked, and as far as Jack's concerned, it's a safe, no-strings fling. But every game has its limits…and Jack is about to discover just how dangerous a dare can get!
