The Return: The Darwin's World Series, Book 4

Contacted by a new civilization, the people on Darwin’s World face a threat that goes far beyond what they’ve experienced before. Even the people of the advanced civilization known as Prime are threatened.

Aided by the computer network known as Central, they turn to the only man who might help them.

Matt, a former soldier, is accustomed to dealing with the advanced civilization on Prime and also the more primitive one on Darwin’s World. He accepts the challenge.

But he will need help, and few are ready to put their lives on hold.

What will happen to Prime? What of the Eden called Darwin’s World? Will they be recognizable after the changes forced by circumstances? But Matt knows what has to be done.

Even if it costs him his family and the world he’s come to love.
