Covenant

On a golden summer morning, Anthony is on a fishing boat with his father when the crack of a rifle shatters the silence. His father slumps forward, blood leaking from his chest. Anthony sees a shadowy figure race away from the shore and vanish in the cover of the trees. On the fifteenth anniversary of his father's death, a mysterious message arrives from an unknown sender that promises to lead Anthony to the truth. But is Anthony's helper the angel he'd been waiting for-- or a devil in disguise?
