Ally loves her job. She makes good money, has great work friends, and lives in the best city in the world. Sure, being an upscale escort has its downfalls. The sex is usually bad, and it's always about satisfying the client's needs, not one's own. But Ally didn't end up in this business for lack of other opportunities. She's good at what she does and is proud she can command a high price for it. What Ally really gets out of it, though, is a sense of freedom, of power and control that she severely lacks in her private life. She's closed off from everyone around her, including herself. Everything gets thrown into chaos, however, when she gets the call for a new client, her fifth of the night. Scott Walker is different. He's a young go-getter executive accustomed to getting whatever he wants. And ultimately he doesn't want Ally's body; he wants her heart. But that's the one thing she refuses to give up. Ally is forced to make the hardest decision of her life: to stay in her comfort zone or step outside it for someone who might just be worth the risk. If you think you've read every story about a hooker with a heart of gold, think again. Sexy and edgy, Client N° 5 will seduce you into the intimate world of a high-class call girl, strutting its stilettos into the raw, erotic territory Pretty Woman feared to tread.
