The book takes place on December 25, 1776, the day when George Washington led the American Army across the Delaware, and it centers on three characters: George Washington, Thomas Paine, and Jonathan Van Dorn (a person I'm pretty sure they just made up). Though I did find myself bored, particularly in Washington's segments, I found myself actually caring what became of Paine and Jonathan. The writing didn't strike me one way or the other. It wasn't bad, but I never found myself thinking "wow, that is a great sentence." (Which is, actually, something I think when I'm reading a good book.)
One thing I appreciated is that Gingrich and Forstchen did not get political in the novel, which made it much easier to read. The introduction made some political statements I didn't agree with (like saying "The modern education establishment has deliberately ignored American-history and minimized the importance of learning about America" p. xv.) but they did not carry into the novel.
I've waffled a lot with my rating for this novel. In the end, I'm giving it a 2/5, but it nearly got a 3. Reading it was not terrible, and, maybe if I liked historical fiction, it would've gotten the higher score. Either way, it definitely seemed like a book my Grandpa would like, and if you're into wartime historical fiction, I might recommend it.
