For Cass, the River is an escape from her isolated life?a shadowy realm where she races through twisted laneways and lives out violent dreams. For Detective Poe, it?s a dark terrain where danger hides behind every corner and the next clue may be his last. Adlai, watching from a bar on its borders, hopes his creation evolves into something more profound. But a rogue musical virus is on the loose, infecting users, growing stronger with fear, and threatening the River?s collapse. As reality and fantasy blur, each must confront what it means to truly feel.
