Query: Korman is the best author I have read since 3rd grade!!!

OMG! I just finished Korman's DIVE series. The books are amazing, and are great for readers around 10 to 17. This series is nerve-racking, and it is one of those books you can't put down. I can't wait to read the next series, EVEREST. It looks great. You will get your money's worth.
