Billion Year Countdown - Matthias Gruber - Bog

Just a few months short of the completion of his final thesis, a student has an unexpected meeting with a mysterious being. This sets off a fateful chain of events, which seems to be connected to a strange plague and to a rogue secret agent.
Reaching the original goal of his intergalactic odyssee, the line between good and evil starts to blur and a new perspective begins to form. It becomes clear that the university of life accepts no final thesis, that instead it is an eternal lecture in which everyone is student and teacher simultaneously.
