This week's sponsor is Garth Stein, author of the bestselling The Art of Racing in the Rain, my favorite book of last year as summarized in this Unshelved Book Club. Turns out people really fell in love with the musings of Enzo, the canine narrator of the story, and so Garth spun up this store with hats and t-shirts featuring choice quotes from the book. My kids both have the Enzo hat, which comes pre-chewed.
