They have found the fabled island continent of Caspak… And now, they might be buried there! Abby Tyler and her research team face an unfathomable scenario: Somehow, they have traveled back in time and have come face-to-face with not only Bowen Tyler himself, but also the evil Baron von Schoenvorts and the crew of the U-33. To their knowledge, World War I still rages outside the walls of Caspak, and von Schoenvorts will stop at nothing to escape the island prison. But will any of them survive being attacked by a pack of vicious Allosaurus?
