The Fourth Visitor

2027. A fourth interstellar visitor enters the Solar System, and this one is slowing down.

Five space agencies and one private founder race to reach it. 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.

They touch it. It falls.

Inside the crater, 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 hard science fiction novel about first contact, institutional certainty, and the decisions that make humanity dangerous. The scientific papers, datasets, and historical observations beneath its central lens are real. Read the novel. Then look them up.
