Saxon Smith is on the research trip of a lifetime in Antarctica to explore a remote ice cave system. A previous expedition found hints that the much warmer subsurface caves could support life and Saxon wants to make that discovery and make a name for himself.
The small team descends into a cavern hollowed out of the ice by volcanic activity expecting lichen and arthropods and maybe the remains of extinct life, what they find is a lost world of dinosaurs that have adapted to the permanent twilight, cool temperature, and constrained location.
The expedition now face a terrifying fight for survival against savage theropods that have learned to herd and trap, and with their ice cave ecosystem starting to fail, they’re ravenous.
