The Fourth Visitor

2027. A fourth interstellar visitor enters the Solar System. This one is discovered early enough for humanity to reach it.

Five space agencies and one private founder race to be first. Publicly, the mission is scientific. Inside closed rooms, every contingency becomes a tool, every safeguard becomes permission, and every institution arrives at the same decision in its own language.

The Fourth is not on a collision course with Earth.

They touch it. It falls.

The impact leaves a crater in Siberia. Inside it, an international team expects broken cometary material. What they uncover is engineered, active, and tied to a record reaching back 140 years: photographs, signals, radar returns, and astronomical anomalies preserved by people who never knew they belonged together.

The Fourth Visitor is a large-scale, global science fiction novel about first contact, institutional certainty, and how individually rational decisions can compound into consequences no one intended. The scientific papers, datasets, and historical observations beneath its central lens are real. Read the novel. Then look them up.
