I've read Charlotte's Web with my kids, but they're still getting used to chapter books so I haven't read the rest of E. B. White's books yet, but I'm really looking forward to them. And Imagination Station, those books look really good! If you're kids like puzzle stories (mysterious letters, messages written in code, etc.), I would recommend trying out Peggy Parish's Liza, Bill, and Jed Mysteries books if you can find them. I read Haunted House as a kid and absolutely loved it! I've also read The Clue in the Woods as an adult and it was really good too.
