On May 1, 1992, Jules Delaney and Quinn Riley hardly know each other. Jules is high school queen bee in a small Midwestern town when she survives a brutal attack by the elusive May Day Killer --- a predator who strikes every May 1st. Quinn, a boy from the wrong side of the tracks, is arrested the same night after trying to break up a fight and nearly killing someone. By morning, their lives are forever connected. A year later, Jules is tormented by one question: Why was she spared? Quinn is newly released from juvenile detention and returns home to devastating news --- the unsolved murder of his mother. Over the next decade, their lives are revisited on a single day each year: May 1st. As the years pass, secrets surface, lies unravel, and the paths of Jules and Quinn draw closer together.
