The artwork on the front cover of the novel is an original acrylic painting I did last year. Natalie (one of the main characters) is an artist and she references Van Gogh once or twice in the novel, so the strong hint of "Starry Night" is intentional. Although this particular painting is not mentioned directly in the story, I did try to give some thought to the way that Natalie might paint this picture if she were sitting in her space in the back room of the thrift store where she works and pondering the line from the Kabbalah: "We hold in one hand a cluster of stars, and in the other a morsel of dust."
I've attached an image of the full painting.
