Definitely Terry Goodkind's Sword of Truth Series, I've read all 11 books 3 times.

Definitely a great read, I also love the Narnia series.

You guys should check out the Broken Sky series. It's my all time favorite fantasy series! The author is Chris Wooding. I have some more of his books, but I haven't read them yet. Anyways, this series has everything! Topics range from revenge to hatred to racism, and themes include parallel worlds, spirit stones, creatures that can move through mirrors and wild monsters such as the Keriags, a giant insectoid species.

The books begin with Ryushi and Kia, twins who have been given powerful spirit stones at birth. They live on a wyvern breeding farm until one day, the empire attacks and destroys their entire village. It turns out that their father was a leader in the rebellion, which Ryushi and Kia end up joining. Most people have spirit stones, which can allow their users to power machines, see the future, move earth into shapes such as golems, which is Kia's power, or even shape the air into a beam of pure energy, which is Ryushi's power.

Unfortunately, the books have been out of print for several years, so you would either need to find them in a library, or get them through Ebay or Amazon. However, there have been reprints of the books within the last year or so, but they're only out in the UK. One might actually be able to find them on Amazon.uk.

My favorite fantasy books are alot of the ones mentionned here. I loved the Lord of the Rings, though it's been ages since I read them now. I should reread them. I also completely adore the Harry Potter series. It has such an enchanted world and the characters are so lovable, (or you hate them visciously) and the twist and turns in the plot keep everything very interesting.

I also really love the Wheel of Time series. I have spent the last year reading the whole series on and off, and I have to say that it was most definately worth it! The characters, the background story, the history, the cultures, the aes sedai and their powers, it's all really fascinating! I am just relieved that Robert Jordan planned out the last book well enough for it to be written and finalized, because I would have been so disapointed if there had been no end to the series. In the meantime, I read A New Spring, which is also a must read, as it gives alot of background story to Lan and Moraine.

And since I have no series to read at the moment, I've been seriously contemplating reading the Sword of truth series. I've heard only good things on this forum and outside of it!

Well, I've read/like a large chunk of the books mentioned so far. I started A Song of Fire and Ice a couple weeks ago and I'm at the end of the third book already. I think my favorite author is probably L.E. Modesitt Jr. though. I guess he's not quite as popular as a lot of other authors mentioned here, but I started with his Recluce series and haven't stopped reading his books. To tell you the truth though, I'm just as big a fan of his science fiction.
