Epic worlds collide in a race against time in this thrilling sci-fi novel from World Fantasy Award finalist Fiona Moore.

Ken Usagi, a daring young journalist from the icy wilderness of Nunavut, is thrust into a perilous journey through the war-ravaged remnants of the former United States. Haunted by a chilling encounter with a mysterious biotechnical machine-a relic from his troubled childhood-he becomes convinced it holds the key to ending the devastating conflict tearing the world apart.

Far to the south, Totchli, a brilliant young biotechnician from a Mesoamerican society pummeled by catastrophic climate change, receives a desperate order. He must venture north to uncover the fate of a critical colonial expedition, a mission that once carried the last hopes of his people's survival. Communication channels with the expedition have fallen eerily silent.

As Ken and Totchli embark on their separate quests, the very fabric of reality begins to unravel. Their paths converge, leading to a fateful encounter where the boundaries of their worlds blur and shatter.

In a race against time, with the fate of two worlds hanging in the balance, Ken and Totchli must navigate a web of secrets, dangers, and cosmic forces that threaten to consume everything they hold dear. Can they unite to save their shattered worlds, or will they be forced to watch as everything they know and love is destroyed?
