Sixteen-year-old Frankie Budge – aspiring writer, indifferent student, offbeat loner – is determined to make it through yet another sad summer in Coalfield, Tennessee, when she meets Zeke, a talented artist who is as lonely and awkward as she is. As romantic and creative sparks begin to fly, Frankie and Zeke make an unsigned poster that becomes unforgettable to anyone who sees it. Copies of their work are everywhere in town, and rumours start to fly about who might be behind the ubiquitous posters: Satanists? Kidnappers? Soon, the mystery has dangerous repercussions that spread further afield, and the art that brought Frankie and Zeke together now threatens to tear them apart.
