Q: This was one of my favorite books assigned in school this year. I like the exciting adventures of this cannon trek from Fort Ticonderoga to Cambridge, MA. I liked how they crossed the ice with all of those big guns. When the last gun crossed, the ice cracked, but they were able to get the big gun out.
A:
Positive
