I started reading Harry potter whe the Chambers os secrets just came out, so i reread so much Harry potter i have no ideia but probably 20x the first 2 books, 10x the third, and the rest 5x.

The kingkiller chronicles is another history because there is no book 3, so once or twice every year i listen to the audiobooks, probably read and listened to the books more then 10x each.

Currently rereading the hobbit and later on LOTR, there is some version of the audiobooks that got the movies soundtrack and effects, its a movie in your mind really.
