Listyboy's 20 Great Book Series

The whole book series thing has been around for a long time, but I blame the modern obsession for them (particularly in the fantasy field) squarely on Tolkien. There's something about a nicely presented series that can fuel one's collector's fever. Only problem is, once you've bought a complete collection, you have to find the time to read the damn thing! I've started reading most of these. Some I've completed. Some I will never complete. How about you? Thanks for checking out the list.
