Excerpts:

The tall false fronts of Main Street spilled out a lake of shadow, a canal of liquid heat that soaked through the iron weave of Collins' jeans and turned into black ink stains. The old window of the hardware store showed its age in soft wrinkles, ripples that had caught on fire in the sunset. Collins felt the twilight stealing under the arms of his tee-shirt. The overdue hair on the back of his rangy neck stood up in attention. It was a joke, but the first one Collins had ever known Doc Candle to make.
