We've been reading the Rainbow Magic Fairy books since she was in preschool. She loves fairies! I always read them to her. I never asked her if she'd want to read them by herself. I'll have to see how she does with them.
Quoting srichtermom:
My daughter loved the Rainbow Magic Fairy books at the age; there are at least a hundred of them. They also having shorter chapter books that go along with the Little House on the Prairie series that were quite enjoyable too. Some other favorites were Magic Tree House and the Baby Sitter's Club Little Sister books.
