Bumped (Bumped, 1)

A virus has swept the world, making everyone over the age of eighteen infertile. Teenagers are now the most prized members of society, and would-be parents desperately bid for "conception contracts" with the prettiest, healthiest, and smartest girls—cash, college tuition, and liposuction in exchange for a baby.

Sixteen-year-old Melody has scored a record-breaking contract with a rich couple. And she's been matched with one of the hottest "bumping" partners in the world—the genetically flawless Jondoe.

But her luck is about to run out.

She discovers she has a sister—an identical twin. Harmony has grown up in a strict religious community and believes her calling is to save Melody from her sinful intentions. All Melody wants is to meet Jondoe and seal the deal—but when a case of mistaken identity destroys everyone's carefully laid plans, Melody and Harmony realize they have much more than DNA in common.

Sharp, funny, and thought-provoking, this futuristic take on teen pregnancy is compellingly readable and scarily believable.
