First book finished was Drek!: The REAL Yiddish Your Bubbe Never Taught You. Now, I speak and read a fair amount of Hebrew. I stumble over the liturgical language in the prayer books, but I know some colloquial language. This book isn't Hebrew, though, it's another language entirely. Most of the Yiddish I ever learned came from my father, may he rest in peace; a bit more from peers who used some of it in conversation. I never learned to read it, and I certainly haven't learned any grammar in it. This book isn't really a way to learn the language, but it contains some juicy material, and reviewing it connected me with Dad in ways nothing else has since he passed. Cool book.
Second was Osprey Fortress #71: The Walls of Rome, which I found interesting, if for nothing more than a bit of geographical information about the town in ancient days. (Note my reading of many books of mystery set in Ancient Rome) A fairly good read.
