Rate this book
Lachlan is an anxious loner, one among thousands rescued from an Earth torn apart by war, environmental ruin, and social chaos. Now living in Commune—a tranquil sanctuary on the alien planet Karnika—humanity is under the watchful protection of the Jiriki, an advanced and enigmatic alien species who offer peace through a philosophy they call “The Remedy.”

But despite Commune's apparent utopia, Lachlan senses hidden truths behind the Jiriki’s motives. When he discovers Nepenthe, a mysterious psychedelic drug coveted by his alien guardians and produced through sinister means involving humans, his doubts deepen into dread. Loyalties blur, friendships are tested, and Lachlan finds himself caught between trusting his mentor, Kalkutun—a curious, compassionate Jiriki scientist—and Sophia, a determined young mother who suspects their alien saviours are hiding something terrible.

As tensions rise and the fragile peace of Commune threatens to shatter, Lachlan must confront his deepest fears and grapple with a haunting Have the humans truly been saved from Earth, or are they merely prisoners, caught in a more dangerous game than they ever imagined?

On Karnika, the truth may be more frightening than the lies—and freedom could cost everything.

Karnika by Nathan McGuinness is the classic warning against not trusting institutions when they say they're doing something for your safety, yet typically abusing their authority to remove your freedoms or monetize you.

It's about a loner who is rescued by an alien race that leads humans by a very interesting ten-point charter called the Remedy. Everything seems to be going well for our main character, Lachlan, until he starts to suspect these folks may not be as innocent and helpful as they seem. Once our protagonist begins questioning the situation, things start to change, and our story really begins to kick in.

It’s a fun read as you get into the head of Lachlan, and McGuiness really makes you feel invested in him and the story. It’s reminiscent of Solyent Green by Harry Harrison, where there is a deeper, darker, more sinister world existing beneath the delusion presented to the masses.

Karnika is worth reading for the Ten Tenants of the Remedy alone. It’s sort of a spiritual Ten Commandments. At times, some of McGuiness’s work isn't as tight as it could be, but the way he skillfully draws you into the story with his plotting and character setups is a lesson in how it’s done.

I found Karnika very compelling for anyone into dystopian sci-fi with spiritual elements.

A Chilling Look at a Perfect Lie

Karnika is a gripping sci-fi story about survival, trust, and hidden danger. Lachlan, an anxious loner, lives on the alien world of Karnika, where humans are promised peace by their strange protectors, the Jiriki. But when he uncovers the dark truth behind a mysterious drug called Nepenthe, everything he thought he knew starts to crumble. The book explores fear, control, and whether true freedom even exists. Some parts moved a bit slow, but the mystery and tension kept me hooked. If you like stories with alien secrets and moral twists, this one’s worth the read.

thought, provoking and atmospheric

Karnika slowly builds unease beneath a seemingly peaceful alien utopia, raising powerful questions about trust, control, and freedom. Lachlan’s inner struggle feels authentic, and the moral tension keeps you engaged throughout. A compelling sci-fi story that lingers after the final page.
