Ice.

SYNOPSIS:
After 16 year old Zack finds out he has an incurable disease, his perfect world suddenly falls apart into a million little pieces. The idea of spending the rest of his life in the hospital crushes him. But there's a solution, or is said to be one. Cryopreservation, also known as a process where cells, whole tissues, or any other substances susceptible to damage caused by chemical reactivity or time are preserved by cooling to sub-zero temperatures, is in need of a test subject.

Desperate for a cure, Zack accepts being the guinea pig for the experiment. He has nothing else to lose, right? But little does he foresee the corruption of the government, plague, and full out apocalypse in the future. Forgotten and helplessly frozen, Zack is found 300 years later in an abandoned city where his hospital lies.
