The ice holds secrets that should have stayed buried. Staff Sergeant Jason Hart's routine Arctic mission shatters when he uncovers a research facility conducting impossible experiments with something vast... and ancient. Dr. Isabel Chen has connected humanity to a network that spans beyond comprehension. But as Hart delves deeper, he realizes this connection comes with a terrifying price: to save our species, we must surrender what makes us human. Trapped between his loyalty to Chen and his own rapidly changing mind, Hart faces an impossible choice. The presence beneath the ice is growing stronger. Time is running out. And some doors, once opened, can never be closed.
