I read a lot- as I'd imagine we all do here- and am always hungry devouring stuff *I've not read before*, so "rereading" is a luxury I usually dont have.
That said, I do find myself, at times between new stuff, returning to the works of Robert E Howard, and Arthur C Clarke just for the sheer pleasure of it.
In comics- too many! The Alan Moore and Jamie Delano Captain Britains, early Spidey, Scalped (which I try to make time for every couple of years), the first 100 issues of Walking Dead (currently enjoying them all over again in the ongoing Deluxe series), and of course any number of 2000AD strips from over the years- currently Strontium Dog, of which I'm on volume 3 of the Agency files after having mainlined everything from the start of the redo from the original prog 2000 to The Son, then Agency Files vols 1 and 2 late last year.
