The crystal planetoids

This audiobook is narrated by a digital voice.

Glowing in the skies above Earth, a swarm of crystalline planetoids descends from the orbit of Saturn—silent, beautiful, and terrifying. In The Crystal Planetoids, Stanton A. Coblentz unleashes a dazzling tale of mid-century science fiction, where humanity faces a threat unlike any it has known. As cities fall under the alien influence and global panic surges, one eccentric scientist races to decode the nature of the invaders and devise a counterstrike rooted not in brute force, but in scientific brilliance.


Told with vintage pulp flair and intellectual verve, this classic novel blends high-stakes adventure with philosophical undertones, asking what resilience, reason, and invention look like in the face of existential peril. The Crystal Planetoids is a cosmic showdown between human ingenuity and crystalline domination—perfect for fans of retro sci-fi, planetary menace, and the golden age of speculative fiction.
