This one is a deep cut, first published in 1951. It begins as a straightforward adventure, with a protagonist tasked with hunting down a dangerous alien that’s gotten loose on Earth. It becomes increasingly clear that something isn’t right, though, and eventually, our hero realizes that he’s actually a replicant, sent to do this job because his original was too cowardly to do it himself, and that his only hope of survival is to murder his original and take his place. I first read this when I was nine or ten years old, and the growing sense of horror as the truth becomes clear has stuck with me ever since, as has the dark, dark twist of an ending. This might be a tough one to find, but it’s well worth the effort. 

It's all about the unlikely alliance between a woman and her clone in this gripping revenge thriller.

Evelyn Caldwell learns that her husband Nathan is cheating on her when she discovers that he has stolen her cloning technology and replaced her with a more docile substitute. They work together to conceal Nathan's murder and preserve Evelyn's scientific reputation.

However, Evelyn discovers her clone standing over Nathan's body and crying, "It was self-defense." Its juicy premise raises eerie questions about love, justice, and the nature of identity.

Speaking of noir, Kiln People is basically Mickey Spillane with replicants. This book posits a future where the well-off use temporary copies of themselves to do things that are dangerous or difficult or just boring. The copies fall apart after a few days, at which point they ideally merge their memories back into their original. Brin’s protagonists are a private detective and one of his copies who decides he’d rather spend the few hours of life he’s given doing something more interesting than his original’s scutwork. I came to this story for the fun premise, but I stayed for the deeper exploration of the morality of creating an army of sentient beings whose only hope is to live long enough to be re-absorbed into the mind that created them.

The Ophiuchi Hotline is the first of four novels set in Varley’s Eight Worlds universe, where bodies are malleable things, and appearance, gender, and even your basic form can be changed on a whim. Its protagonist, Lilo, begins by escaping her execution by allowing an illegally produced replicant to die for her. Her situation deteriorates steadily from there, as she is repeatedly killed and resurrected while passing through the belly of the solar system’s underworld.

This book hits all my sweet spots—a morally ambiguous protagonist, an imaginative plot that provides a running commentary on the many ways we’re making a mess of the present world, and, as a bonus, someone getting chucked into a black hole for making a new kind of food called “bananameat” out of human DNA. What more could you ask?

This book takes everything amazing about the mystery genre and transposes it into an endlessly fascinating, well-developed sci-fi world. I was captivated by the web of interconnected plot lines, told from the perspectives of rich and multi-faceted characters throughout the entire story.

Specifically, the fact that all of their seemingly disconnected backstories converge to form the real picture of the story was masterfully done. Furthermore, the final reveal of the story was quite literally the only plot twist in fiction that has given me a verbal “oh my god” moment.

It was a massive inspiration for me and led to my love of a combination of morally gray mystery, sci-fi, and action adventure.
