Ruby Caldwell, a plus-sized, neurodivergent Australian time travelling journalist and has always been drawn to forgotten stories. When a mysterious locket linked to the long-unsolved disappearance of Elsie Harper a young woman lost in 1920s Sydney lands in her hands, Ruby discovers she can slip through time. Transported to the night of Elsie's vanishing, she witnesses the crime unfold firsthand and realizes the historical record has been manipulated.
She is joined by her fiancé, Daniel Mercer, a fellow journalist who also possesses time-travel powers. Together, they navigate a dangerous world of corrupt officials, shadowy power brokers, and societal prejudices, racing against history itself. Their primary adversary is Inspector Elias Harrow, a timeless figure who profits from chaos and covered-up crimes, manipulating events across eras to keep the truth buried.
Ruby draws guidance from Miriam Cross, a retired war correspondent who teaches her that journalism isn't just about telling stories but choosing which stories matter. In the present day, Detective Mark Renshaw, a pragmatic cold-case investigator, becomes an ally despite his disbelief in time travel. Ruby is supported emotionally and humorously by Juno, her childhood friend and podcast producer, who keeps her grounded with sarcasm and levity. Dr. Aidan Holt, a historian of unresolved events, becomes fascinated by Ruby's knowledge of the past and provides crucial insight, though he struggles to reconcile her abilities with reality.
As Ruby and Dan gather evidence and untangle the mystery, their differing approaches threaten to fracture both their partnership and their relationship. Dan's ambition nearly costs them everything, forcing him to confront his fatal flaw and choose justice over glory. In the end, Ruby's determination and Dan's redemption ensure Elsie Harper's story is finally told. They return to the present forever changed, having learned the weight of truth, the cost of meddling with history, and the enduring power of love and partnership.
