Across Realtime

First published 1986 · 560 pages

A mind-expanding leap through deep time that blends hard science fiction with a locked-room mystery at the end of the world.

What it feels like

Reading this collection feels like standing on the edge of a temporal cliff, watching the centuries blur past in a dizzying rush. The narrative blends the rigorous, idea-driven speculation of hard science fiction with the tight, urgent pacing of a locked-room mystery. There is a profound, lingering melancholy to the atmosphere—a deep sense of isolation that comes from being unmoored in time, surrounded by the silent ruins of a vanished civilization. Yet, beneath the existential dread, a current of relentless human resilience drives the story forward. The prose is pragmatic and sharp, designed to deliver massive, mind-bending concepts with absolute clarity. It is a perfect fit for readers who crave vast, cosmic scales, temporal paradoxes, and the thrilling intellectual puzzle of the technological singularity.
