In all the Katie Kazoo books Katie turns into something such as, the class hampster, one of her best friends Jermey and the principal to name a few. In this book Katie turns into Suzannes baby sister, Heather. I feel like all the Katie Kazoo books just POP at you the way she turns into things!
Nancy Krulik style of writing, is just so amazing! I spent the whole summer reading this series. This was the first one I read. It was awesome!!!!
