42. 24 Karat Kids

Again, chick lit, but fairly decent chick lit... here's the B&N description:

Meet Dr. Shelley Green - newly minted pediatrician. After graduating medical school at the top of her class, Shelley is hired by Madison Pediatrics, the Upper East Side's most exclusive practice. Suddenly this self-described 'schlumpy girl from Jackson Heights' is thrown into the world of the rich, famous, and very neurotic. Her life is about to change in a big way.
Hyper-parenting has reached epidemic proportions -- and Madison Pediatrics is its over-privileged epicenter. Shelley, a superb doctor with a kid-friendly touch and a genius for diagnosis, quickly becomes the Upper East Side's latest must-have accessory, the darling of the fabulously-wealthy-with-kids crowd. Now she's slimming down, dressing up in Fendi and Prada, and weekending in the Hamptons. No wonder Arthur - her adorable schoolteacher fiancé - is baffled.

Enter Josh Potter - blueblood hunk who never seems to have his checkbook around. What he does have is charm, connections, and enough sex appeal to set Shelley's head spinning. Before long, Shelley's plate is way too full: men and medicine, elite nursery schools and rooftop swimming pools. Can she handle it all without losing her soul? Find out in this delicious dose of fiction that brims with acerbic wit, dead-on satire, and finally, poignancy and heart.

Not the best I've ever read, but the main character is pretty likeable, despite some not so good decisions on her part and the stories about the uber rich patients she works with are pretty funny. A good beach read...
