A mysterious disappearance, an enormous fortune and a Czech oligarch - it's the weirdest and wildest challenge yet for Janet Evanovich's bestselling sleuths Fox & O'Hare

FBI Agent Kate O'Hare plays by the rules. Charming con man Nicholas Fox makes them up as he goes along. They're working together to tackle the out-of-bounds cases ordinary FBI agents can't touch. And their relationship? Well, there hasn't been so much explosive chemistry since Nitro was introduced to Glycerin.

Next up: the mysterious disappearance of the Silicon Valley billionaire known as the Big Kahuna. His model wife and shady business partner are more interested in gaining control of his company than in finding him. They need a dead body... not a living Kahuna.

The only lead is the Kahuna's drop-out son, who's living the dream in Hawaii. To get close to him, Kate and Nick go undercover as a married couple in the surfer community. For Kate, there is nothing more horrifying than setting up house with Nick Fox. If they don't catch a break soon, waves aren't going to be the only thing she'll be shredding (or bedding).
