About this book:

Inheriting her enigmatic clockmaker father's London workshop, Evelyn Thorne discovers more than dusty gears and silent timepieces – she uncovers a peculiar pocket watch capable of reversing time. But this extraordinary inheritance comes with a chilling cost, each use of the watch distorting reality and exacting a physical and temporal toll on Evelyn herself. As whispers of this impossible device spread through Victorian London's gaslit alleys, Evelyn is thrust into a perilous game of cat and mouse with a clandestine organization known as the Chronos Keepers, who will stop at nothing to seize the watch and control the very fabric of time.

Faced with ruthless adversaries and unsettling clues in her father's cryptic journal, Evelyn must decipher the secrets behind his untimely death and the terrifying potential of his final invention. Teaming up with the pragmatic Inspector Davies of Scotland Yard, who reluctantly accepts the impossible truth, Evelyn races against an accelerating clock. They uncover a plot of catastrophic proportions: the Chronos Keepers plan to use a network of temporal anchors across London, culminating at Big Ben, to initiate a "Convergence" – a terrifying reset of the city's timeline.

The pursuit leads Evelyn to confront a chilling revelation: the architect of this devastating plan is none other than a future, emotionless version of herself, created by the watch's relentless toll. With time literally unraveling and London on the brink of being unmade, Evelyn must confront her own terrifying potential and utilize the true, hidden failsafe her father built into his paradox – a power far greater and more resilient than temporal manipulation itself.
