Seven Blackwood doesn't believe in ghosts. He believes in logic, in proof, in things that can be recorded and explained. So when his friends dare him to visit a sealed staircase in their old college building at 3 A.M., he goes-just to prove them wrong. But something calls his name from the dark. His phone records nothing. His friends hear nothing. And six minutes vanish without explanation. Every night after that, he dreams of the same staircase. Only this time... it isn't sealed. What happened between 3:03 and 3:09 might not want to stay forgotten.
