Unfortunately LLATL is never clear as to how to schedule their book studies. We are doing Gray at the moment. I try to look ahead and see if a book study is coming up and then I work backwards to see when I have to start assigning the chapters to be read. We aim to finish the book just before the actual book study appears in the student book. So for instance, DD is reading "A Lantern in her Hand", two chapters a day, and needed to start reading four weeks before she will do the book study. HTH
