Crying wolf?

For Nat and his new friends, Grace and Izzie Zorn, twin sisters as seductive as they are elusive, it was the perfect plan for some quick cash. A bold scheme with an admirable motive: to save the bright future of a deserving young man. And the victim, too, was deserving--an arrogant billionaire who would hardly notice a financial loss.

For someone in the shadows is listening, someone who thinks he deserves an even brighter future. Now a risky but basically innocent game will take a horrifying turn. . . .
