I love the Dinotopia books! The worldbuilding in them is just so amazing, you can't help wishing you could live there!
I have the four big picture books, and they're all fantastic! I wish the YA novels were still in print--I wouldn't mind collecting them, too, though I'm sure nothing can top the gorgeous illustrations in the main series.
Funny, I actually got into Dinotopia through the TV movies when I was a kid...for a while, I had no idea there were books.
Nowadays, though, Zippo is pretty much the only aspect of those TV specials that I still like. (I would've rather seen more of him than the human characters, he was practically the only character who had an actual personality!)
