Self-professed nerd Maddie Maloney is an expert on jewels. When a mysterious Englishman warns her that a thief known as The Chameleon is after the rare pink diamond on display in her aunt's shop, she tells herself it's just a joke. Even if she can't get Mr. Tall, Dark and Sexy out of her mind...

Fabian Montgomery is everywhere Maddie goes, convinced the thief will strike. When the diamond does go missing—and Maddie is suspected of stealing it—he whisks her away from the police and together they pursue The Chameleon. Fabian plunges her into a glamorous world far from her humble workshop and transforms geeky Maddie into a sophisticated siren capable of espionage. Her mission: to seduce The Chameleon and steal back the diamond.

But Fabian isn't telling her everything—like who he works for, and why he's so interested in The Chameleon...
