I just finished reading this amazing book, and I loved it! This book is about a girl named Winnie, who's parents are a bit difficult. Winnie's parents are too alike for their own good, and they want everything to be equal. For instance, when Winnie came home from school and her parents told her that they were getting divorced, they had a duct-tape X on the couch for her to sit on, exactly between her parents. Since her parents are getting divorced, they inform Winnie that she's going to have an EXACTLY equal amount of days with each of her parents, by switching off between their new houses each day of the week. But, since there's seven days in a week, Winnie's going to spend that one extra day living in a treehouse, exactly between her parents' houses. At first Winnie thought the idea of living in a treehouse was ridiculous, but then she realized that it might be nice to have some peace and quiet. Then stuff got even crazier. Winnie usually spent Thanksgiving with her family, as the one holiday they celebrated, but since her parents weren't living together anymore, they had to celebrate a new holiday. First Winnie celebrated a new holiday with her Mom, then Winnie's dad got jealous of her mom celebrating the holiday with Winnie, so HE decided to celebrate a DIFFERENT holiday with Winnie. So that's how it happened that every day of the week Winnie celebrated a different holiday, so she had no time for her homework, or anything else. But there was one exception - on Wednesday's she lived in her treehouse, so she could relax, draw, cuddle with her cat, and do her homework, things normal kids did every day. But since there was only one Wednesday each week, Winnie was falling behind with her schoolwork, because every day (except Wednesday) was spent celebrating a holiday. Her teacher said that Winnie might even fail fifth grade! Her teacher gave her an important history report to do, and said if she didn't ace it she would have to redo fifth grade. So Winnie was under a lot of stress, until her final breaking point. Winnie's dad wanted Winnie to spend the summer with him, so to make up for those days with her dad, Winnie's Mom said that Winnie would spend every Wednesday with her, until the time from the summer was made up. This Winnie could not handle, because Wednesday's were her only time for normal things, and she would fail fifth grade if she didn't get a good grade on her history report. By chance Winnie learned that technically her treehouse wasn't a part of the US, so it didn't follow the rules of the US either. So, Winnie went up to her treehouse when her parents told her this, and it wasn't a Wednesday. She decided to stay up there until her parents came up and talked to her together about the whole holiday every day of the week thing, like levelheaded adults. Then Winnie's friends joined her, all because of something they wanted their parents to agree on, like more video game time, or more attention. And since her treehouse was technically its own country, no one could come into the treehouse unless the kids approved. After the kids had been in the treehouse for a couple days, "The Treehouse Ten" became famous. Will the kids come down from the treehouse, or will they stay up there until they get what they want? I really loved the format of this book, it was really cool. The book was told in Winnie's perspective, in the style of a journal, with fake sticky notes every few pages, written by various people in the Treehouse Ten. My favorite character was Winnie, because she seemed really smart and levelheaded in this book. I would recommend this book is to late elementary and middle school readers. Enjoy!
