I've just finished Shellie Zacharia's collection Now Playing. I'd call the collection more simple than not, though I don't mean that in a negative way. I found it refreshing. The characters are honest and straightforward, and there's a recurring theme of guitar players and teachers. There are a lot of stories here (28) comprised of seemingly equal parts flash fiction and short stories.
Several of the stories stood out for me: "Take," "Luckily, Lucy Sims Has No Stamps," "Cyrus Is Spinning," and "Cardboard Ben."
