Zoe Gaston needs to unmask a mystery man for work. She also must survive her dreaded high school reunion--and the costume party that opens it. So Zoe, once voted Girl Most Likely to Die a Virgin, comes dressed as a leather-clad dominatrix... whip and all!

But Zoe is shocked to discover the sexy body she's been so thoroughly enjoying belongs to Dexter Drake--her oldest friend! And he's hiding something bigger than just his identity....
