Taminy,
A friend of mine has used Great Books and loves it. She is trying to get it started at DD's elementary school for next year, but her work schedule has changed, so we don't know if it will work. I don't know a lot of details about it, but my friend has 4 gts and her older two really got into it.
My DD6 also spend way too much time on independent reading this past year even though she was grouped with other "strong" readers. There was only 1 girl in her class anywhere near her, so the teacher finally let them pick a more advanced book and read it together and then they acted out the book while she read the story to the class. The girls loved it and the teacher was very impressed with how well they did. I just wish they got to do more of that sort of thing.
