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 cleverest girls - cash, college tuition and liposuction in exchange for a baby.

Sixteen-year-old Melody is gorgeous, athletic and has perfect grades, and has scored an amazing contract with a rich couple. And she's been matched with one of the most desirable 'bumping' partners in the world - the incredibly hot, genetically flawless Jondoe.

But Melody's luck is about to run out. She discovers she has a sister - an identical twin, Harmony, who has grown up in a religious community opposed to the idea of 'pregging'. Harmony believes her calling is to save Melody from her sinful plans. Melody doesn't have time for this - she can't wait to meet Jondoe and seal the deal. But when he arrives and mistakes Harmony for Melody, everyone's carefully-laid plans are swept out of control - and Melody and Harmony are about to realise they have so much more than just DNA in common.

Sharp, original and sassy, this futuristic take on teen pregnancy is totally readable and scarily believable.
