The Diary of a Wimpy Kid by Jeff Kinney is hilarious! The series has become so popular. But Greg Heffley, the main character, is in middle school. So, the experiences he writes about in his journal may not be appropriate for younger readers. Of course, his ‘journal entries’ are from a boy’s perspective as well. Don’t worry though, there are other books with the same quirky sense of humor for girls and younger children to read!
