I've re-read all of Jane Austen several times.
I have re-read Straight Man by Richard Russo three or four times, but it's still not out in e-version.
When a book in a series I like comes out, I'll re-read the others to refresh my memory (not as young as I used to be, lol).
I have over 700 books on my Kindle and I'm still re-reading stuff, lol.
Right now, Portal by Imogen Rose.
I think I'm going to re-read the Frank Tuttle books soon because I find them hysterically funny. And I don't even like fantasy
