Discontented and unfulfilled, Imogene meets Henry Bishop by chance, and his sister Aggie, the embodiment of everything Imogene wishes she could be. However, when Aggie goes missing unexpectedly, Imogene and Henry come across her journal, which sheds light on Aggie's fragile state of mind in the months leading up to her disappearance. Imogene and Henry then embark on a perilous journey to find her, while beginning to uncover dark and frightening secrets hidden in the rugged outback, and also answers about what really happened to Marella Fuller, the day she disappeared.
