The Painting That Wasn't There Book

Although the protagonists in this book are sixth graders, this is definitely a book for kids who are just starting to read chapter books. The story and the characters are very simple. The mystery, although absurd to an adult, would probably be enjoyed by a first or second grader. I would definitely add this to my collection of first chapter books. It's unimportant that the kids are older, they act like any kids - and would totally be embraced by a younger reader. The book has all the elements of a mystery, and would be a good read aloud when introduction the genre to a first or second (or perhaps even third) grade class.
