Maya Quinn thought she knew every shadow on her street, every familiar creak of the old apartment walls. That was before the man next door arrived—calm, watchful, and impossible to read. He wasn't just a neighbor. He was something else entirely, and his presence began to bend the world around her in ways she couldn't explain.

A chance encounter sets her on a path into hidden corridors beneath the city, places that don't appear on any map. The deeper she goes, the more the line between safety and danger blurs, until home no longer feels like home at all. Whispers follow her. Faces she doesn't know seem to recognize her. Doors appear where none existed, and behind each one lies another truth she might not survive learning.

Every choice pulls her further from the life she knew, forcing her to navigate a web of secrets where trust is dangerous and every answer demands a cost. In the space between what's real and what's hidden, survival means understanding who is watching—and why they've chosen her.

A pulse-pounding urban thriller, Next Door Devil grips from the first page and never lets go, unraveling a mystery that will linger long after the last chapter.
