A thrilling, hilarious adventure across time and space, from the beginning of the universe to its many possible pasts and futures. When humanity disappears from existence, Kim Anena, Un Sinn, Gita Singh, Professor Gerard Hilt, Ignatius Fulanodetal, and the rest of the Temporal Research Division of the Society for the Advancement of Knowledge and Understanding, are faced with paradoxes and permutations in time that defy description. And the situation only gets worse as they use a time portal called the Hole to find out what is really going on and how they can undo the damage.
