Bog Standard Isekai

Mark’s new life begins in the worst possible place—a burned-out village haunted by undead. Each morning these ravenous creatures disappear, only to return at night, driven by a relentless hunger. He'll need to stay low and think quick, because trapped and alone in the body of a child, he can’t level up in this new world. At least not yet. Soon Mark will learn that even among the living, safety isn’t guaranteed. When the small town that he ends up in turns out to be at the center of a conspiracy that threatens the world, he'll need to uncover the truth before it's too late.

Brin is scarred, but no longer alone. After giving up his evil Rare Class in exchange for the simple and common Glasser, he’s finally been accepted by the people of Hammon’s Bog. But acceptance doesn't guarantee safety. Mirrors and glass spearheads offer little protection against threats both outside and within. An army of undead is lurking in the surrounding forest, cutting them off from the rest of the world. There’s no rescue in sight, and worse, no one knows why the army is there or when it will attack.
