In the "New Ark", the last bastion of mankind, memory is a commodity available for trade, and eternal life is the promised ultimate benefit.
Ling Zhou, a top "soul master", is responsible for extracting the memories of the deceased and sending them into the so-called paradise - the "Eternal Palace". When his only relative, his terminally ill sister, was also selected into the project, he glimpsed a terrifying truth about using souls as food.
The so-called immortality is nothing but a well-planned scam. The elites are above the clouds, enjoying a feast made from the memories of countless civilians.
In order to prevent his sister from becoming the next sacrifice, Ling Zhou must resist. He will turn against the entire city and confront the tyranny that controls memory. From the cold extraction room to the gleaming memory black market, from the abyss of humanity to the battlefield of consciousness, his only weapons are the love and memories of mortals that are regarded as cheap.
When the tide of memory sweeps in, can he protect the last reality?
