Special Service Agent Chance Mitchell and Detective Natalie Gibbs like it when their jobs require them to change their appearance and play a role. Chance also likes working with Natalie solving cases. He doesn't like the overpowering need to have her, though, and the only way he knows to get her out of his mind is to have her -- just once. Natalie also feels a strong attraction for Chance and jumps at the opportunity to spend just one night with him.

Three months later, Chance is back in DC. His goal is to convince Natalie to work another case with him. And since he hasn't been able to get her out of his mind for the last three months, he needs to see her again. When Natalie hears Chance is in town, she wants to see him. But not as herself, since he so easily forgot about her three months before. Changing her appearance, she becomes Rachel Cade, Natalie's cousin who's outgoing and outspoken. Chance, however, knows "Rachel" is really Natalie and plays along. And because she'll be able to spend more time with him, she agrees to help him with his case.

Undercover on the extremely dangerous case, Chance becomes Steven Bradford, a software billionaire, while Natalie (playing Rachel) becomes Steven's current love interest, aspiring super-model Calie Weston. Never once does Chance tell Natalie he knows who she really is. Instead, he falls for each of the three women she's become. Natalie doesn't reveal who she really is because she's sure he'll leave her again once he finds out, since she believes he found Natalie lacking before. She's sure once the case is finished, she'll never see again the man she's fallen in love with.

What an extremely sexy and exciting story! The characters have such great chemistry, and the storyline is fast-paced. This book will be one I keep on my shelf to read again.
