Query: One of his best!

I love books about books so Dunning is right up my alley. I've read his previous two books and enjoyed them so when I got "The Bookmans Promise" I was expecting another good read. I got that and more! Kept me spellbound trying to figure it out (and I'm usually pretty good at that!). I was so caught up in the story and changing scenes that the ending came as a total surprise. Love the history and it truly made me want to do more research on the subject. This had more heart and twists than the previous two and is definitely worth reading. I may do it again!
