Onslaught from Rigel: A Positronic Book (Hardcover) (ISBN-13: 9781515425588)

A catastrophic event transforms humanity overnight, leaving Earth vulnerable to a relentless alien assault in this fast-moving science fiction novel of survival, adaptation, and counterattack. Fletcher Pratt wastes no time dropping the reader into crisis: a sudden and unexplained upheaval alters the human condition itself, scattering survivors into a world they barely recognize. Before they can fully grasp what has happened, an extraterrestrial force from Rigel moves in, turning confusion into open conflict.

What follows is a tightly driven narrative of resistance under impossible conditions. Pratt excels at combining strange speculative ideas-physical transformation, environmental instability, and alien intervention-with the pacing of pure pulp adventure. The stakes escalate quickly, moving from personal survival to planetary defense, as humanity struggles to regroup and respond to an enemy that has already reshaped the battlefield.

First published in the early 1930s, Onslaught from Rigel stands as a vivid example of pre-Golden Age science fiction at its most energetic and imaginative. It delivers both the wild conceptual reach of early speculative fiction and the forward momentum of invasion storytelling, making it a strong addition to any classic science fiction list.
