I've reread all my children's books- several times, or I've given them away. Am not quite sure why, but I return to some of my children's books quite often. Basically all of Astrid Lindgren's work and "From Anna" and the books I have by Tonke Dragt.

I tend to reread not so high literature books more often, because mostly I am just looking for a bit of distraction, and with most of them I don't mind to know the story.

And strangely there are some books I'll never forget which I could never reread though. They are too dense or so. The "Kite Runner" e.g.
