The Time Keeper: Library Edition

The inventor of the world's first clock is punished for trying to measure God's greatest gift. He is banished to a cave for centuries and forced to listen to the voices of all who come after him seeking more days, more years. Eventually, with his soul nearly broken, Father Time is granted his freedom, along with a magical hourglass and a mission: a chance to redeem himself by teaching two earthly people the true meaning of time.
