Terror Beneath the Ashes. Horror, #11

Terror Beneath the Ashes is a gripping YA horror novel set in Grayglass, a town rebuilt over buried lava tubes after a deadly eruption. When ash begins to fall upward and eerie doubles walk the streets, sixteen-year-old geology prodigy Raine Okada uncovers a terrifying truth beneath the town-and beneath her own past. As ancient rules resurface and names become weapons, Raine must confront grief, fear, and a living horror that feeds on breath.
A tense, atmospheric story of survival, identity, and the cost of silence.
