Book One The Moons of Pohjola - KUUTAR (en Inglés) - John Bailey

The forest is not attacking the colonists. It is adopting them.

Kuutar is the fog-moon of the Pohjola system: an engineered world of vast conifers, inland seas, and a gas giant filling half the sky. Eleven years of colonial work have made it beautiful. The Caduceus disaster, two years prior, seeded it with something that has been growing in the water ever since.

When ISC physicist Dr. Cord Valen leads a four-person scientific team to Kuutar to investigate seventeen reported medical anomalies, they find the real number is closer to four hundred - and rising. A novel isotope called V-119 has entered the settlement's water table and, through it, the biology of anyone who drank from it. The transformation it produces is unlike anything in any medical framework: colonists are slowly incorporating the cellular structures of the engineered conifers. Bark-texture skin. Chlorophyll-adjacent compounds in the blood. In the most advanced cases, full physical integration with the root network.

The horror is not that the transformation is grotesque. It is that it is not. The colonists who are furthest along feel no pain. They feel better than fine. One of them, rooted to a tree in the deep forest, says: "I can feel the whole forest. Every root. Every tree. It's like having a very large body. I don't know if I want to be saved."

Valen's team - engineer Dougal Ferris, terraformer Takeshi Oru, communications officer Lena Parish, and xenobiologist Dr. Aiko Harukawa, who has been on Kuutar alone for nine weeks waiting for someone to listen - must work against three forces simultaneously: the contamination spreading through the root network and the fog, a colonial administration determined to manage the narrative rather than the crisis, and a corporate liaison whose company filed a prior-knowledge report and sat on it.

Kuutar is science fiction in the tradition of careful, human-scale horror - slow, atmospheric, and ultimately about the question of what we owe each other when the catastrophe was not an accident but a choice.

The Moons of Pohjola is a trilogy. Books Two (Päivätär) and Three (Tuoni) continue the story.
