25 years from now, an infertility virus has infected nearly everybody, rendering them sterile by 18. However, humanity must go on, which means the reproduction is entirely up to teenagers. This is America, so there is nothing that can't become commercial, and girls line up lucrative contracts with adult couples to have babies for them with designated, professional partners. Melody is just such a girl, the first in her school to go pro and sign such a contract. She's an over-achiever and a trend-setter, but the couple who contracted her services still hasn't found a suitable male. Which means Melody is 16 years old, not pregnant, and running out her biological clock. In a stroke of luck, Melody gets matched with the ultra-desirable Jondoe--but it's her identical twin sister who gets the message. Harmony was raised in Goodside, an isolated religious community, and has sneaked away from that life in order to find--and save--her sister. Unsurprisingly, things get messy, especially since nobody was supposed to know about Harmony's existence. 
 Okay, where to begin. For something that's arguably dystopian (condoms have been outlawed for 10 years by the events of this book; all teen sex should be procreative), it's remarkably fluffy--chick lit jumps on the dystopian bandwagon. The future-slang is ever-present and irritatingly precious, starting from the title, Bumped. And I'm not entirely sure why there are all these layers and drugs to help girls block out the weirdness of the sex-for-profitable-procreation--have we lost the technology for IVF, or artificial insemination? Lots of plot threads wrap up in predictable ways, while still leaving the situation open enough to allow for a sequel. 
 There's plenty here to make a really deep, conversation-worthy dystopia: a virus that makes people infertile by adulthood, commodification of pregnancies, gender roles, population control, religious observance--but instead all these topics are brushed aside so readers don't need to worry our pretty little heads about such weighty matters. What we're left with is a run-of-the-mill light romance that wouldn't be the slightest bit noteworthy if the characters itching to get pregnant and have these babies were in their 30s instead of their teens. Sexual content is not graphic, but it does drive the plot, making this an iffy choice for teen library collections, particularly if the demographic skews younger. Older teens interested in the ideas would be better served with The Handmaid's Tale.
