The The Aeonia Enigma

When Marcus Kyriakos inherits a villa on the remote Greek island where he was born, he intends only to settle his late uncle's affairs and return home. Instead he finds himself drawn into a world of ancient rites, buried memories and competing loyalties. As the island's secretive Circle begins to take an unsettling interest in him, Marcus discovers that his uncle may have spent decades preparing for his return. But on Aeonia, the past is never truly past. And some invitations cannot be refused. As old wounds reopen and forgotten truths emerge from the shadows, Marcus must decide whether he is an outsider looking in-or the missing piece of a story that began long before he arrived.
