Fishing around for some new reading material, and remember that a RAFO Top ## list had been discussed, figured I'd do two for one.

For my part I don't like stand-alone too much, one book and it is done, and even a trilogy doesn't always get a very flushed out universe so I'll specify some conditions:

1. Must be composed of at least 4 books, and a trilogy plus an anthology or lone prequel should be avoided.

2. Is not the novelization of some movie, TV series, or video game like Star Trek or Star Wars or Star Craft, or for that matter a RPG like Forgotten Realms, Dragonlance, Warhammer 40k, etc.

I'm also going to disqualify a handful for just being so common on these sorts of lists or conversation that they're redundant to talk about, and aim for lesser known ones.

I'm doubtless leaving off some there, feel free to add them, and obviously your mileage may vary on those. Certainly mine does, I've either read all those, tried reading and didn't get into it, or tried it and hated it. I'll include my own lesser known ones with why I liked them in a follow up, what can you add and why would you add it?
