Twins always finish each other's sentences. Especially in prison. Ex-Marine Tracie Vossler thought working prison security would be safer than combat. She was wrong. When identical twin inmates and an ancient body-swapping demon collide, Tracie's only priority becomes keeping her twelve-year-old daughter alive-no matter the cost. A demon that wears human faces. A prison that cannot contain what is already inside. Set against the claustrophobic dread of a 2020 corrections facility during the Covid pandemic, Blood Echoes is a slow-burn supernatural horror where combat training and institutional protocol prove useless against a force older than reason. What would you sacrifice to save your child? One mother's brutal reckoning unfolds as prison horror, demonic mythology, and a love fierce enough to bend the boundaries of identity itself collide. From the author of the Dissonance alien-invasion saga and The End dystopian series, Blood Echoes tracks a single mother navigating a demonic conspiracy inside a real Washington state prison-where the scariest thing isn't the monster, but how far she's willing to go.
