4.0

I wasn't sure what to give this one because I really liked it, but I didn't finish it (gave up trying and returned it to the library after renewing it twice). I didn't get bored, exactly...more like I have a quota for how much Civil War introspection and trivia I can stomach in a year, and I reached it about 3/4 of the way through. Anyway, I recommend this book for someone who is more historically-inclined than I am (i.e., basically everyone).
