Even after hundreds of years as a Time Keeper, Grant Stone still doesn't know much about his charges, the shadowy aliens known as Time Wraiths who live in clockwork clocks. Like the other Keepers in the world, he is only aware that these mysterious beings can devastatingly affect humanity by altering the perception of time. Because of this, their jobs are to keep mechanical clocks working for the good ones to live in and trap the bad ones in clockwork vaults to protect the world. This all changes when someone enters Grant's life. A type of Keeper that had never existed before reveals more about the Time Wraiths than they had ever known, and uncovers a danger that lurks nearby that threatens wraiths and humans alike. Can Grant convince the other Keepers of this approaching danger as he observes a sudden change in the wraith's behavior after centuries of living with them?
