The Great Demon System

Daniel Cross thought he had everything. Twenty million dollars. A luxury penthouse. A beautiful wife he loved with everything he had. Then his wife, Vivian Hale, and his best friend, Gavin Rourke, betrayed him. They used him for his money, stole everything they could from him, and finally drove a knife into his chest when the world had already begun to burn. Daniel died with hatred in his heart. Then he opened his eyes. Thirty days before the Great Scorch. This time, Daniel knows exactly what is coming. In one month, an unprecedented heat wave will scorch the entire planet. Temperatures will soar to unimaginable highs. Electricity and water will fail. Food will disappear. Cities will become burned-out graveyards. And ninety-five percent of humanity will die.

With twenty million dollars in the bank, memories of the apocalypse, and a mysterious Storage Space that can preserve anything he puts inside, Daniel begins preparing for the end. Food. Water. Ice. Medicine. Fuel. Weapons. Cooling gear. Everything he needs to survive. He will turn his luxury penthouse into an impenetrable fortress and stockpile enough supplies to survive for years. But Daniel isn't preparing to save the people who betrayed him. Vivian and Gavin think they can still manipulate the foolish man they once used as their personal ATM. They have no idea that the Daniel Cross they knew is dead. When the temperature climbs past a hundred and sixty and civilization collapses, they will come knocking on his door. They will beg. They will plead. They will remember the man who once loved them. But Daniel has only one question for them: After everything you did to me, why should I save you? This time, he won't be the prey.
