I listened to most of this one on a road trip to my grandparents' house, and it was an engaging story on audio (I've found this to be rare!) -- stories about quirky, likable old men seem to keep popping up on my radar -- but I liked the angle of this one with the books as these remedies and prescriptions for ailments only Monsieur Perdu seemed to sense in folks. It's a sweet story and one I enjoyed but wasn't obsessed with.
