I'm trying something new this summer. Ambleside "slow reading" has been such a good experience in the homeschool that I'm trying to overcome my usual inclination to devour a book apace, remembering only a general atmosphere and a few vague details, and instead, make myself a sort of "course of study" with a variety of different books which I read a chapter or so at a time. I'm even trying to narrate to myself after reading, though that's sort of like pounding my head against a wall.
How is it working, aside from the headachey effect of attempting mental narration? I'll let you know. I'm working against long-established habits here, but I do enjoy the time and space to ponder when I go through the books more slowly. It's something like walking along a road rather than running full pace. Sometimes running full pace is exhilarating, so I will try to occasionally include the "read in a 3 hours sitting" type books. The last one of that sort I read was The Curious Incident of the Dog in the Night-Time, mentioned by laughingstars. I have to remember to finish everything that needs doing BEFORE I start on one of those, though.
