King in Limbo Omnibus 1

Eight years after a mysterious illness called the Sleep killed millions worldwide, a pandemic-ending treatment that involves diving directly into patients' memories has become standard practice. Petty Officer Adam Garfield, newly discharged from the U.S. Navy after losing a leg to an IED, hopes to retire quietly and spend time with his younger siblings. Instead he is called back into service: the Sleep has returned, and Adam is tasked with tracking down the reclusive man known only as King, the figure credited with ending the sickness the first time.

This omnibus collects volumes 1 and 2 of Ai Tanaka's science fiction thriller manga.
