Every 24 hours, a teenager vanishes.

Every clue leads to a dead end.

Every clock in the city stops at 3:17 a.m.

Detective Luna Voss is the best the department has, but the kidnapper is always two steps ahead, until the night she and Kieran Hale, a quiet archivist nursing a hopeless crush, accidentally shatter a forbidden time machine hidden beneath an abandoned clock tower.

Now they’re trapped in a merciless loop: the same kidnappings, the same failures, the same deaths, repeating until they get it right.

Each reset erases the world’s memory, but never theirs.

Each cycle brings them closer to the truth, and to each other.

The mastermind? A brilliant horologist who believes teenagers are the key to cracking time itself.

The final piece? A brass puzzle box Kieran inherited from a father he never understood.

To break the loop, Luna and Kieran must outthink a genius, save the missing kids, and decide what they’re willing to lose forever, because in the Crime Loop, the only way out is to change the past without destroying the future.
