Candidate Four (Bidden #1)
Crystal Cierlak

So when her glamorous, dresses-like-she-isn't-hurting-for-money co-worker Quinn offers her the opportunity to make a lot of money for just one night of work - a "job" that is as secretive as it is lucrative - Natalie is hesitant, but curious.
Twelve glamorous “Candidates” line up for twelve gentlemen bidders in a luxurious, private residence high in the hills above the city. The item up for auction? One night with a Candidate.
He pays, she stays. What they do is up to him.
Is the lure of cash enough for Natalie to lay herself aside for one night as Candidate Four?
