So my "Books I'm Reading" widget wasn't working out so well for me - I usually finish a book pretty quickly after starting it that it was rare I'd get around to listing it before I was done with it. I don't know why it took me so long to figure out that I could have the widget list books that I'd recently finished instead of books I am currently reading.
Just look to the column on the right and there's a list of all the books I've finished for the month. My attempts at a weekly post summarizing books I finished for the week didn't last long, but just author and title I can handle. If you're curious about any of them, just let me know and I'll write something up about it.
