Sweet Revenge by NORA ROBERTS Romantic Suspense PB 2006

At twenty-five, Princess Adrianne lives a life most people would envy. Beautiful and elegant, she spends her days dabbling in charities and her nights floating from one glamorous gala to the next. But her pampered-rich-girl pose is a ruse, a carefully calculated effort to hide a dangerous truth.

For ten years Adrianne has lived for revenge. As a child, she could only watch the cruelty hidden behind the royal facade of her parents' fairy-tale marriage. Though nothing will bring her legendary film star mother back, Adrianne is consumed by one thought: to make her father pay. In his possession is one of the world's greatest treasures, a fabled necklace beyond price - the Sun and the Moon. But not for long... For Adrianne has made it her business to develop some unusual skills. And now she's about to take a final, irreversible step.

Yet just as she is poised to taste the sweetness of her long-sought vengeance, she meets a man who seems to divine her every secret. Clever, charming, and enigmatic, Philip Chamberlain has his own private reasons for getting close to Princess Adrianne. And only when it's too late will she see the hidden danger... as she finds herself up against two formidable men - one with the knowledge to take her freedom, the other with the power to take her life.
