The Empire is splitting at the seams. The Great Houses refuse to obey the Throne World and have begun to conduct increasingly independent politics. Sensing the weakness of the central government, even the most loyal star systems of the Imperial Core are refusing to take orders from above.

Who of the many figures in intergalactic politics can rise to this challenge?

In the 18th century, the British minister and mathematician Thomas Bayes devised a theorem that allowed him to assign probabilities to events that had never happened before. It languished in obscurity for centuries until computers came along and made it easy to crunch the numbers. Now, as the foundation of big data, Bayes's formula has become a linchpin of the digital economy. But here's where things get interesting: Bayes's theorem can also be used to lay odds on the existence of extraterrestrial intelligence, and on the biggest question of all: how long will humanity survive?
