Moon Shard Reclaimer

After the moon shatters, the resulting gravitational imbalance causes “lunar shadow tides” on Earth. Every night at midnight, everyone gains three seconds of memories from their own selves in a parallel universe. The government hires “reclaimers” to erase these memories, but one female reclaimer discovers that every time she carries out a mission, another moonlit scar appears on her wrist, invisible to everyone else.
