My niece and nephew both liked You Wouldn't Want to Be a Medieval Knight, and my nephew even requested a re-read. I was pleased with this one, too, because while it did show some blood with knights in battle, it was less "in your face" than You Wouldn't Want to Be an Egyptian Mummy
. That one was heavy enough on the "eeeww factor" that I've yet to read it to the kids.
You Wouldn't Want to Be a Medieval Knight seemed to strike my nephew as being less scary and more cool than You Wouldn't Want to Be a Roman Gladiator
, and he was extremely impressed with how cool the knights and warhorses looked in their armor. He identified with our gallant knight protagonist throughout the entire book, clear up until the end when he was shown as an aged hero. "Amy, I'm not that knight anymore. I don't want to be old," he said. Yeah? Join the club, Boy. I know how you feel.
