Dynasty Of Killers (DOK)

Maia Faucigny never thought she'd return to the town where her father was brutally murdered twenty years ago. But when she stumbles upon his cryptic research and a series of unsettling emails exchanged with a mysterious "Mr. H," her life takes a dangerous turn.
Determined to uncover the truth, Maia finds herself back in her father's hometown, where she unexpectedly crosses paths with Ryo Lee, a troubled celebrity whose life is on hold after a career-shattering scandal, and old acquaintances Kim Haejin and Haru Adachi.
Forced into an uneasy alliance, they uncover a powerful enemy manipulating time itself using the Temporal Conduit-a device that threatens to erase Maia's family from history.
As they unravel the mystery, they become targets of forces willing to kill to protect their secrets.
With the tension escalating, Maia realizes that her father's death was no coincidence and that stopping the deadly plot spanning centuries, could mean saving not only her family's past but also her present and future.
