Meet the Kid Sisters. They're great friends — most of the time.

Sarah Chinn, Naomi Kaufman, Rivky Segal, and Melissa Farber are inseparable. At least they were until Rivky got moved into the other fourth grade class in the Bais Yaakov of Bloomfield. Will the Treehouse Kids be able to stay friends? Rivky misses her friends. Sarah is too involved with her birthday to come to the treehouse. Can Melissa’s secret plan patch things up? Join Sarah, Rivky, Naomi, and Melissa as they learn about Growing Up.

Rivky’s got some good news and some bad news. The good news is that she’s finally getting used to her new fourth grade class. The bad news is that her old friends aren’t — and they’re mad at her! Melissa has trouble of her own when her brother gets engaged. Read all about it in Changing Places.

Naomi and Rivky were once best friends. But not anymore. It’ll take something really special to get them talking to each other again. But special things always happen to the Treehouse Kids. Join the girls for their best adventure yet in Missing!
