Her Prince by Sidney Bristol

Once upon a time there was a brave princess and a smart gypsy boy who saved the day… Kade Tsaplin left behind his nomadic family to live a different kind of life—one where he doesn’t have to read cards and lie for his next meal. When a beautiful woman with adventure in her eyes crash lands into his life, the last thing Kade expects is to get drawn into one of his brother’s cons. But Shelby is more than she appears, and makes him an offer he can’t refuse.

Shelby Amos is an art thief trying to right the wrongs of her past. Kade’s supposed to be a means to an end—an accomplice she can trust on this most dangerous undercover job. With Kade’s help bringing down a criminal mastermind she might finally get the answers she’s been searching for. Only, she never counted on falling for Kade. Working both sides of the job takes its toll, until Kade and Shelby find themselves in a den of thieves, with only each other to rely on. As danger draws them closer, the lovers unwittingly play right into the spider’s web, handing over the true prize—Shelby herself.
