Wow - you guys are making me feel lame. I just finished the third book in "The Edge Chronicles," a series targeted at probably early teens. I read the first two a while ago after liking the Series of Unfortunate Events books, and had to read the third one to finish out the first trilogy.
I'm now reading the third book in David & Leigh Eddings' series "The Dreamers." I was reminded fairly quickly that this series is kind of weak, even if you're a fan of their work, but oh well. I have read pretty much everything he/they have ever written (he used to just put his name on everything, but later said "you know what? My wife has really been a big part of writing these books" and started putting her name on all of them too.
Guess I'm in "finish old series" mode right now.
