We loved the literature in Sonlight when we used it. We own Core K-2. What kept us from using it in the future was the expense AND that I couldnt see how to combine my children who are so close in age but not close enough to share a core. They are 8, 7, 4,2, and 1. And I didnt want to do two cores. LOL. We are using My Fathers World which so far has great literature, hands on ideas that I was always adding into Sonlight and is much cheaper because one Year combines Music, Science, Lit, History/Geography and Bible then you have a book list to fill in additional Readers and Read Alouds bringing the cost down by nearly half!. :) Which is a major reason for our switch that and its laid out nicely because each "grid" schedule is followed by all the discussion quesitons and teachers notes, no flipping back and forth. And Maps ect are printed in the back and the recommend you print them out ahead of time for your map work. With SL I was constantly printing maps because the children LOVE To color them and lable. :) Anyway I feel I have the best of both world.
