Query: Good stuff!

Hey i'm only 16 but i read this book and thought it was good. It was a great concept. I like David Brin. I read Startide Rising and that was awsome!!! I gave it 4 stars because at some small parts it was slow. It caught my attention cause all of the good comments on the back like: "Better Than Dune!" so i read it to see if it was. Not quite in my opinion but it comes to an equal.
