Query: IMPOSSIBLE TO PUT DOWN

The sinister tone of the prologue lets you know you are in for a dark look at the possibilities of egg retrieval and cloning. Deborah Cochrane and Joannna Meissner, roommates and fellow Harvard grad students, answer an ad to donate eggs (for a hefty price of $45,000 each.) After their year-and-half stay in Venice completing their theses, they return to their recently purchased condo in Boston, all financed with the proceeds of their donations. Curious about their progeny from the egg donation, they set out to learn about their children. The Wingate Clinic has strict confidentiality rules, however, so they devise a clever plan to change their identities and pose as job seekers at the clinic. Their plan is hilarious, and along with the great suspense, I fell in love with the characters! The girls were just so naive, but had such a good time throughout the book. I read it in one day. It was impossible to put down!
