I am not sure why, but we have gotten out of the habit of reading chapter books. The kids & I both love it, but I think we have just been so busy that I let that slide. Part of my rationale was to encourage Catherine to read more on her own, but she is not doing so. I decided to revert to one of our favorite authors, Roald Dahl. In addition to his most well known books, he has written many novellas. I had actually never heard of most of these, but we have thoroughly enjoyed them. Most of them we can read in one sitting, or at most two sittings.
