Query: exciting book

The Matchlock Gun, by Walter D. Edmonds,was an exciting book. There was a gun in their family, from Spain, that was longer than a man, heavy, and fired like a canon. Edward, the main character, was fascinated with the gun and felt lucky to have it in their family.When his father is gone with the militia, Edward is responsible for the family as the head of the house, but he is only 10! Edward and his mother were scared because they thought Indians might attack, sneaking through the militia.I was scared reading the ending, but when it was over I wished there was more.This was a good book for 8 year olds or older, because of some violent things. I give it 4 out of 5 stars.
