Last night I began #31 - Three Came to Ville Marie (1941) by Alan Sullivan. Weirdly, the font in this book is VERY LARGE, and I think if anyone on the subway were to look over my shoulder at what I was reading, they would think I'm reading a large print book. Or a children's book.
I was worried that I would never get this book, because for months the only copy available seemed to be a used one on Amazon Marketplace for over $300! However, my enterprising mother (or Santa) found some print on demand version in England for a more reasonable price.
