Children's books recommendations

My son asked me today to find him some good books to read.  He said he wanted anything about dinosaurs, snakes, or adventures (there was one other thing he said, but I don't remember what it was.  I think it was another "A" word though LOL).  He is 8 years old, but reading at a fifth grade level.  He reads very fast too (knocked out the last Harry Potter book by Thursday of the week it came out!), so we need as many suggestions as possible!  Thanks in advance for any ideas.

It sounds like your son loves to read so he may have all ready read the Narnia books. If not, they are enjoyable reading for any age. Whittington by Alan Armstrong is about a boy and his seafaring cat. It's based on history but not in the least boring. Good Luck!
