Finished Return of the King last night with the now 8 year old. Absolutely one of the best experiences of the (pretty difficult) last school year or so. That's a pretty tough set of books to read aloud, but man, so rewarding.
Moved on to Babe, which ought to be a little more palatable for both boys. We also still have some Bad Guys books from the library that got put on hold for a bit that we will likely break back out. Might suck big sister back into reading with Dad with Narnia or The Green Ember soon.
