N's adventures continue in this second volume. After defeating the Devil, the Empress of the Underwasteland finds herself facing a group of elves in search of a new homeland. Unlive or undead? Don't mind, the catastrophic awakening of an ancient undead brings an end to the eons of the dungeon as we know it.

The Underwasteland is the hell at the edge of the universe. In the house in the middle of an ash desert, N inherits the title of [Empress] of the Underwasteland. Her tasks are as important as they are monotonous: judging the deceased and taking care of the immense dungeon in which they rest. N's life is boring and lonely until a [hero] offers her an umbrella. "When the time comes, avenge me" is what he asks in return. Between colorful encounters and difficult moments, N must complete at least a thousand years of mandate as [Empress]. A difficult task since some sleepers are more dangerous dead than alive.

Sous chef Aimee Tierney has the recipe for the perfect life: marry her childhood sweetheart, raise a family, and buy out her parents' restaurant. But when her fiancé, James Donato, vanishes in a boating accident, her well-baked future is swept out to sea. Struggling to reconstruct her life, she delves deeper into James's disappearance. What Aimee uncovers is an ocean of secrets that make her question everything about the life they built together. And just below the surface is a truth that may set Aimee free... or shatter her forever.
