Twins always finish each other's sentences. Especially in prison.

===

Ex-Marine Tracie Vossler thought working prison security was safer than combat. She was wrong.

When identical twin inmates and an ancient body-swapping demon collide in Blood Echoes, Tracie's only priority becomes keeping her twelve-year-old daughter alive — no matter what it costs her.

A demon that wears human faces. A prison that can't contain what's already inside. Blood Echoes is a slow-burn supernatural horror set against the claustrophobic Covid pandemic dread of a 2020 corrections facility, where Tracie Vossler discovers that some threats can't be stopped with combat training or institutional protocol.

What would you sacrifice to save your child? Blood Echoes follows one mother's brutal reckoning with a force older than reason, weaving together prison horror, demonic mythology, and a love so fierce it bends the boundaries of identity itself.

From the Christian author who brought you the alien invasion hexalogy Dissonance, the Christian dystopian saga The End, the epic space opera series The Talisman and nearly 50 other books, Aaron Ryan's Blood Echoes doesn't flinch. Part procedural thriller, part occult nightmare, it tracks a single mother navigating a demonic conspiracy inside a real Washington state prison during a pandemic — where the scariest thing isn't the monster, but how far she's willing to go.
