Ummmm........All of them? Wheel of Time is a great series, but very involved. I've read the Obsidian Chronicles this year which is a great trilogy about dragons amd revemge. Little Green men is an interesting book about a guy who uncovers the governments involvement with alien abductions. Asking which is the best is like asking what kind of chocolate is the best. They're all great because they all have something to offer.
