Max's class wrote non-fiction books. Max's is about D-Day. I've had two parents stop me to ask if he really wrote about D-Day - they seemed to find that much more interesting than the frogs, dogs and other animals that most kids covered!

The Navy fired on the Germans.
The U.S. sent U.S. soldiers!
The planes bomb! British helped the U.S. bomb the Germans.
