Hi everyone! I'm looking for new books for my 4 year old boy. He was reading basic words by his second birthday and now enjoys reading almost anything in front of him. He recently finished all of The Magic Treehouse Books. He was reading about 1 or 2 per day.

It's been hard to find books with appropriate content for a 4 year old (he just turned 4). He has an extremely vivid imagination and intense fears. He's done okay with most of The Magic Treehouse books, but we've had to talk to him about some of the scary things.

He does love non-fiction, but I'm having more trouble finding good fiction books for him. Any suggestions would be great!!
