I so second this one. I brought the whole series off Amazon a while ago and they were and some still are, my motivation for learning faster.
Just to list some other light novels that my Japanese roommate has recently turned me on to (a lot of them are basis for anime, as he's pretty much an otaku

)
1. 灼眼のシャナ (Shakugan no Shana)
2.ゼロの使い魔 (Zero no Tsukaima)
3.とある魔術の禁書目録 (to aru majutsu no index) (index is the reading of the kanji there, though you right them "kinsho mokuroku")
4.キノの旅 (Kino no Tabi)
and one that I'm looking forward to starting sometime when I finally have more time is:
どらドラ!
Also, for the people who have seen Zero no Tsukaima or Shana and didn't like the anime, let me tell you that the books are so much better. To quote my roommate: "The only good thing about the Shana anime was the music." And when we watched the zero no tsukaima anime together, he did nothing but complain the entire time about how much they skipped and did wrong.
