What it feels like
Reading this book feels like having your mind stretched across the cosmos. It balances the dizzying, awe-inspiring scale of a galaxy where intelligence itself is dictated by physical location with the grounded, gritty reality of a medieval alien world. The narrative moves at a brisk, urgent clip, driven by the looming threat of an incomprehensible cosmic horror and the desperate race to save a handful of stranded children. The prose is dense with groundbreaking ideas, from early internet-like communication networks to pack-mind aliens, yet it remains deeply invested in the emotional survival of its characters. It is a tense, wondrous, and intellectually thrilling experience, perfect for readers who crave big-idea science fiction that never sacrifices high-stakes adventure or truly alien perspectives.

About the book
Thousands of years in the future, humanity is no longer alone in a universe where a mind's potential is determined by its location in space, from superintelligent entities in the Transcend, to the limited minds of the Unthinking Depths, where only simple creatures, and technology, can function. Nobody knows what strange force partitioned space into these "regions of thought," but when the warring Straumli realm use an ancient Transcendent artifact as a weapon, they unwittingly unleash an awesome power that destroys thousands of worlds and enslaves all natural and artificial intelligence.
Fleeing this galactic threat, Ravna crash lands on a strange world with a ship-hold full of cryogenically frozen children, the only survivors from a destroyed space-lab. They are taken captive by the Tines, an alien race with a harsh medieval culture, and used as pawns in a ruthless power struggle.
