After the age of interstellar colonization began, the most terrifying possibility was that humanity would be alone in the universe. Fortunately, that did not happen.
The second most terrifying possibility was discovering that every alien civilization was younger than humanity.
That second possibility did come true.
The colonists took this as a sign of humanity's good fortune and expanded without restraint.
But even good fortune runs out.
If you enjoy the intricate histories of different civilizations among the stars, rather than fast-paced hard sci-fi packed with obscure terminology, perhaps you can give this book a try and experience a slow-paced space opera in its richly imagined universe.
