I have a 9 year-old son who is a voracious reader, but I still like to read to him in the evening so I choose chapter books that I grew up with. We have read The Cay, Where the Red Fern Grows, My Side of the Mountain, and The Westing Game. I am looking forward to sharing A Wrinkle in Time with him, too! And a couple of years ago we went through ALL of the Beverly Cleary (Beezus & Ramona/Henry & Ribsy) books. For more recent titles I know the kids are loving the 39 Clues series, as well as the Percy Jackson series. Good luck!
As a young reader I enjoyed reading Little House books, it started a long lived interest in historical books. My daughter really enjoys reading the American Girl books, she really enjoyed knowing I read these same books as a kid. It is a pleasure to watch her get lost on an adventure and instill the importance of treasuring things from the past. I can't wait for her to be ready to read books like Nancy Drew, Ronald Dahl books, and other wonderful books!
