The Coptic Echo: the Echo Cycle, Book Two

Elena Marro has spent three years trying to disappear — and guarding the last piece of a machine that lets the living witness the past. Then a billionaire builds his own version and prepares to give it to the world, with no idea what it truly does.

Elena knows. To stop him she must reach a hidden Coptic lineage that has kept the secret for two thousand years — and is being hunted, betrayed, and killed one keeper at a time by an ancient order that will stop at nothing to seize what they protect.

From the monasteries of Egypt to the coast of Ireland, The Coptic Echo is a fast, literate thriller about grief, faith, and a truth that can no longer stay hidden.
