A young girl, chosen to be sacrificed to the demon queen Ayasi, has escaped. And the immortal's wrath threatens to consume the mountain kingdom struggling to appease her.

A few years later, as sickness spreads across the land, Michewah, who trades in rare medicinal herbs, finds herself in the wrong place at the worst time. A bloody incident in the weekly market forces her to follow the instigator: an old man who transforms into a woman with an unnerving bearing and hollow, white eyes.

It's the demon Ayasi, detached from her supine body and roaming the earth as the Wandering Death. The hours that follow contain the unthinkable as the young woman becomes all that stands between an entire civilization and a force that can end it.
