When Earth receives its first reply from the stars, the message is only one number: –273.15.
Absolute zero — the temperature at which all motion stops.

As panic spreads across a fracturing world, a Norwegian LOFAR operator is sent aboard Aletheia to silence humanity's last message in a bottle, the voyagers. His only companion is NOUS, an intelligence as unsettling as the signal itself, a presence impossible to read.

But as the mission drifts deeper into the void, quiet unease gives way to doubt, and then to a colder suspicion: that the real mystery is not what answered from the stars, but what waits aboard the ship with him.

Aletheia is a haunting work of philosophical science fiction about first contact, artificial intelligence, and the limits of perception — a slow descent into isolation and the possibility that reality itself cannot be trusted.
