My family might be weird but sometimes we basically have our very own book club. Luckily my husband and I like children's literature. Sometimes I have to preread books to make sure they are appropriate for my younger son...sometimes they aren't that inappropriate just not necessary for a 9 year old to read. But many times they are fine. Sometimes my 13 year old will let me know if he has read it. Once all of us have all read the same book we do sit around and discuss it, sometimes over dinner, sometimes in the car.
This started when my older son was young and homeschooled...he would insist I read books he loved and then lead the discussion. I fondly recall a book "club" discussion on captain underpants as one of our first.
