Nothing to say that hasn't been said already. Sam Beckett leaps into the body of an ancestor in the year 1776. I could imagine Sam and Al saying all the dialogue within this book, with the exception of a few curses. I also couldn't picture Sam killing a few people throughout, as I don't believe that was part of his moral standards.
To simply knock them out, I can see, but to instantly shoot someone before they fire first and then have Sam think to himself, "I had no choice" felt very out of character, but it was still a good read, compared to what I have read from the series so far.
I will say, I get that it had to be done, but there were too many instances where Sam was growing attracted to his great great and so-forth Grandmother and had to keep telling us, the reader that he can't partake in anything because it would be incest, regardless of the fact he's in someone else's body.
Anyway, I would recommend for a quick July 4th read---though Sam doesn't really spend any time in the battleground setting. Still, some good writing from John Peel, known mostly as a DJ.
