Radiance by Catherine M. Valente — Summary & Review

Radiance isn’t your average sci-fi adventure. It’s a sprawling, baroque puzzle of a novel set in an alternate universe where humanity started exploring space in the 1800s, and every planet in the solar system is teeming with life—Venus, Mars, even the Moon, which is the Hollywood of this cosmos. This isn’t shiny, futuristic sci-fi with sleek ships and clean tech. Instead, it’s a dusty, gaslit carnival of pulp fiction, silent films, and a solar system that feels both alien and strangely familiar.

At the center is Severin Unck, a documentary filmmaker who’s tired of her father’s overwrought Gothic romance movies filled with ghosts and melodrama. She’s the rebel in the family, chasing truth through the lens of her camera instead of cheap thrills. When she sets out to investigate a vanished diving colony on Venus, her journey becomes more than just a mystery—it’s a deep dive into the nature of storytelling itself.

Valente doesn’t just tell you a story; she makes you piece it together through a kaleidoscope of formats—scripts, press clippings, transcripts, promotional blurbs, and business records. It’s like reading a dossier on a lost film that may or may not have existed. This fragmented style can feel like assembling a jigsaw puzzle with pieces from different boxes, but it pulls you deeper into the world’s textures and contradictions.

The novel plays with the blurry line between fiction and reality. In this universe, movies aren’t just stories—they’re events that shape how people perceive the world and themselves. Severin’s quest is as much about uncovering what’s real as it is about confronting the stories we tell to make sense of loss, identity, and the unknown.

The solar system itself is a character—lush, strange, and full of life. Venus isn’t a scorching hellscape but a place of underwater colonies and mysteries beneath the waves. The Moon is a bustling studio town, where the Edison family’s iron grip on talking pictures forces filmmakers into creative rebellion. Planets and moons alike are alive with their own cultures and secrets, evoking the pulpy charm of early sci-fi but with a modern sensibility.

Reading Radiance is a bit like watching an old film reel that’s been spliced with new footage, out of order and sometimes grainy, but mesmerizing. It demands patience and curiosity. The payoff is a richly immersive experience that challenges how you think about stories—not just as entertainment but as living, breathing forces that shape reality.

This isn’t a novel for someone who wants a straightforward plot or tidy resolutions. It’s a literary labyrinth that rewards readers willing to get their hands dirty with narrative fragments and thematic puzzles. If you’re up for a story that’s as much about the act of storytelling as it is about space exploration, Radiance delivers a one-of-a-kind experience.
