You know a book is good if you only stop reading so that you can tell the author, at 1 a.m.via Facebook, how much you are enjoying it. The evening I began reading it, I’d plans to watch Doctor Who, which, if you know me, is serious business. I thought I would read a little, then turn on the TV. No, I kept reading. Let it be known: Gregory Spatz’s new story collection, Half as Happy, is a wonderfully gratifying little book.
