I really liked the first book in the Death Gate Cycle series, but I didn't really care much beyond it. Each book is in an entirely different realm, and the first one was really captivating. The next one I read, though, just didn't hold me. But the first book is good, at least.

Allie, that Shannarah book I got from your mom is good if you basically want Lord of the Rings with different characters xD
