I agree with the suggestion Farmfamily just made. We've taken to collecting a variety of readers for our children. On our shelves you'd find readers from Abeka, Keepers of the Faith, McGuffey, Christian Light, as well as the Pathway readers. Our children have loved reading through these on their own. They are thick enough that your daughter could put a bookmark in them, read a little each night, and at the end of the week she'd have a
book finished. Now, the books are mostly collections of short stories, but seeing a bookmark moving from front to back might still give her the heady feeling of reading a whole big book.

A few of the readers at her level might have stories that span several chapters.
Part of post removed by board moderator per board rules. Their chapter books are more "graded" than most with which I'm familiar. I personally find some of the R & S books to be a bit bland (comparable to rice cakes,

), but my children have enjoyed them, and the writers are careful to keep the wording simple in the earlier books. If they do use longer words, they often break them up into syl-a-bles (well, they wouldn't probably do that word, but you get what I'm saying

)
It's great you have such an eager reader on your hands! : )
