The Round Door

A little girl named Charli has a ghost friend, DJ. Charli falls ill with the chicken pox and has to stay inside. A round wooden door appears on her bed, under the sheets Charli and DJ have hung up to make a cubby house. The magical door opens into a tunnel that leads to her brother's cubby house, one he has built with his mates in the backyard. Cooper has been having lots of fun without Charli. But now Charli and DJ have some fun of their own, playing funny tricks on the boys!

Copper, Charli, and her six-year-old ghost friend, DJ, are so excited to stay with their Nanna and Pop at their beach house for a few weeks. One day when Charli, DJ, Copper, and their friends decide to swim at a lake, they discover a willow tree that holds an exciting secret. When they decide to climb the tree, a round door suddenly appears. After Charli, DJ, and the others decide to investigate, they are transported to a water park that holds a great adventure with cool sea animals who soon show them how much fun can be had with just a little magic.

The Tree House is the book 4 in the Round Door series. It is one of my favorites. Charli and DJ end up in the jungle with some very funny characters. Some have attitude, some are annoying, and some are just hilarious.
