A novel by

 
 
The UK-led vessel makes the first manned journey through hyperspace, landing on a barren world filled with alien ruins. What begins as a bold expedition quickly descends into unease — one crew member begins to hear voices, glyphs match the original hyperspace schematics, and the ruins seem less destroyed and more... deactivated.
Back on Earth, Dr. Miriam Varquez makes a disturbing discovery: the drive isn't meant to
travel — it's meant to seal. Meanwhile, Russia and China race to launch their own jumps, opening new doors into the void. As mysterious energy signatures begin pulsing beneath Antarctica, the UK bluffs its way into forming a global Hyperspace Consortium. The book ends with a strange signal reaching back to Earth from deep beneath the ice.
