I thought I knew everything I needed to know about Abraham Lincoln, but this novel made me rethink parts of his life. It blends historical facts from the Civil War with fantastical elements—it’s basically a long conversation among 166 ghosts, including Lincoln’s deceased son. I got new insight into the way Lincoln must have been crushed by the weight of both grief and responsibility. This is one of those fascinating, ambiguous books you’ll want to discuss with a friend when you’re done.
