Absolution Gap

In Alastair Reynolds's "Absolution Gap," humanity endures centuries of horrific plague and a brutal interstellar war, only to face an even greater threat: the Inhibitors. These ancient, alien killing machines, stirred from eons of slumber, commence their systematic cull of emergent intelligences across the galaxy, with mankind as their latest target. As remnants of humanity flee the initial waves of destruction, a desperate journey leads them to an apparently insignificant moon. There, they uncover an 'avenging angel,' a girl born in ice who holds the key to mankind's survival and the power to confront their deadliest foe. Meanwhile, on a distant planet, colossal travelling cathedrals pilgrimage towards the perilous fissure known as Absolution Gap. Amidst this unfolding cosmic drama, an unsettling truth emerges: to overcome one existential threat, humanity may be forced to forge a dangerous alliance with something far more terrifying. This epic space opera delves into themes of survival, sacrifice, and the moral complexities of interstellar conflict.
