Civil War books in odd places

I guess you just never know where you'll find that next Civil War book. My wife and I were in Big Lots of all places the other day and I found a copy of Father Abraham: Lincoln's Relentless Struggle to End Slavery for a bargain price of $5. The book was written by Richard Striner and published by Oxford University Press . I haven't searched for reviews on it but there are nice words from James McPherson and Harold Holzer on the jacket. I've got more than enough to read so what's one more really? Keep your eyes open...that treasure may be in a place you're not expecting.
