As a sex addict, Lily Calloway must do the impossible. Stay celibate for 90 days. Cravings and fantasies become her new routine, but while Loren Hale recovers from his alcohol addiction, Lily wonders if he'll realize what a monster she really is. After all, her sexual compulsions begin to rule her life the longer she stays faithful to him. Progress. That's what Lily's striving for. But by trying to become closer to her family - people who aren't aware of her addiction - she creates larger obstacles.

She's addicted to sex. He's addicted to booze... the only way out is rock bottom. No one would suspect shy Lily Calloway's biggest secret. While everyone is dancing at college bars, Lily stays in the bathroom. To get laid. Her compulsion leads her to one-night stands, steamy hookups, and events she shamefully regrets. The only person who knows her secret happens to have one of his own. Loren Hale's best friend is his bottle of bourbon. Lily comes at a close second.

Rose Calloway thought she had everything under control. At 23, she's a Princeton graduate, an Academic Bowl champion, a fashion designer, and the daughter of a Fortune 500 mogul. But with a sex addict as a sister and roommate, nothing comes easy. After accepting help from a producer, Rose agrees to have her life filmed for a reality television show.

Two years will change them forever. When rumors spread like wildfire - like having three-ways with her boyfriend's rock climbing brother - Lily Calloway spirals into a dark place. Her bedroom. Loren Hale is more confident and determined to keep their sex life private, even from their friends, and he helps Lily in the only way he knows how. But how much love is too much?

Ryke Meadows, meet Daisy Calloway... she's all grown up. Twenty-five-year-old Ryke Meadows knows he's hard to love. With a billion-dollar inheritance, a track-star resume, and an alpha-male personality - he redefines the term likable asshole. But he's not living to make friends. Or enemies. He just wants to free climb three of the toughest mountains in Yosemite without drama or interruption.
