194 passengers. 24 hours. No memories. One deadly countdown. Dr. Joshua Hammond wakes up on a flight with no idea who he is-only a glowing green implant ticking down from 24 hours. Everyone on board has lost their memory. Everyone has the same timer. When the plane lands in a ghost city and passengers start dying, the race to escape becomes a race to uncover the truth. A supposed safe zone may hold answers, but the deeper Joshua and fellow passenger Amy dig, the more sinister the puzzle becomes. The clock is lying. And what's waiting at zero isn't survival. For fans of Blake Crouch and John Grisham.
