In southern Greece in 2004, a close-knit group of archaeologists searches for the buried traces of a formidable ancient power. A student running from a failed marriage and family, Ben Mercer is a latecomer to their ranks, drawn to the charisma of the group's members—to the double-edged friendship of Jason, the unsettling beauty of Natsuko and Eleschen, and the menace of Max and Eberhard. But Ben is far too eager to join the excavation project, and there is more to the group's dangerous games and dynamic than he understands. And there are things that should always remain hidden.
