In the follow-up to the visionary Hospital, Yang Wei discovers that there’s more to the mysterious hospital than meets the eye—and none of it is as it seems.

Yang Wei wakes to find himself still a patient at the hospital. Somehow, he’s aged decades overnight and is confined to the geriatric ward on a massive Hospital ship as it floats along a bloodred sea full of unsightly things. But human remains and sea nymphs are perhaps nothing compared to the goings-on belowdecks.

The doctors are nowhere to be found, replaced by a procession of medical robots from whom, of course, no information can be gleaned. So Yang Wei, along with a small group of patients—all just as aged as he is—venture out to explore the uncharted depths of the ship and the answers that are surely hidden within.

As they delve deeper into both the ship and why they’re on it, every uncovered secret comes with its own questions. The only thing Yang Wei can be sure of is that the more he learns, the less he understands…and the less he truly wants to know.
