I enjoyed the book the pace of the story was good it didn't drag, The information about Abraham Lincoln was interesting and unknown to me. I think the characters could of been worked on a bit. Professor Baldwin was one sided you didn't learn till the end that an ex-boyfriend had taken her on a drug raid or taught her to fire a gun. I couldn't get a mental picture of her looks or style. The sub-plot related to rock robberies could of been developed more this plot only received a line or two every now and then. But overall it was a book I would enjoy reading again.
