The First Candidate (The Bidden Series #4) by Crystal Cierlak

Description

Every affair begins somewhere… When a class assignment calls for designing a profit-earning business plan, James Fitzgerald and his classmate – the cool and secretly provocative Audra Robertson – decide to take things a step further: a legendary, for-one-night-only party in a gorgeous mansion high in the hills of Los Angeles at $20 a head. The party is a success, but it’s in a secret room above the pounding music and flowing alcohol where the night really begins and history is made: The very first auction. 

Twelve beautiful girls in golden colored masks. Twelve horny college guys with disposable income to burn. James makes the first bid on the first candidate, a stunning blonde whose identity he’s sure he knows. But it isn’t until they’ve begun to consume their lust-filled passion that James realizes she isn’t who he thought she was…
