Abraham Lincoln: Vampire Hunter, by Seth Grahame-Smith, Grand Central Publishing, 2010.
Someone gave me this book, and I did not have high expectations for it. So that I liked it at all rather surprised me.
I have a law/library background, so Abraham Lincoln is one of my heroes. I was not going to like anything that made him appear ridiculous. This book, amazingly does not. It ties bits of Lincoln's personal history together with an underlying vampire story, and it works. The book was rather well-written, fun to read, and somewhere between silly and thought-provoking.
