The Hamilton Triplets—Madison, Park, and Lexington—are accustomed to living in the public eye. Heiresses to a billion-dollar media empire, they have been raised in New York's most elite social circles and, at 16, know firsthand the demands of being celebutantes. There are people to impress, appearances to make, and paparazzi to outrun. Not to mention high school to finish.

But when fashion editor Zahara Bell is found dead in a one-of-a-kind frock from Lex's unreleased clothing line, and then the priceless Avenue Diamond goes missing, getting to class is as far from the triplets' minds as their first pair of Manolos. One of the girls is a suspect, and the sisters find themselves in the middle of a scandal that could sink their reputations and their father's companies for good. And the press is ready, willing, and able to lend a hand.

The Hamilton sisters need to stick closer than ever before. The killer is still out there, and if they don't solve the case their threesome could become a twosome quicker than you can say Cartier.
