Join les on the journey.

COMING NOVEMBER 2025 (Hardcover)

Hugo Award winner Ben Bova and Les Johnson complete Bova's Outer Planets series (Uranus, Neptune, and Pluto), a Grand Tour of the human settled solar system, with a final encounter on Pluto.

Major Larry Randall has been called to Pluto to retrieve Dr. Aaron Mikelson. Mikelson, no longer human after a horrific accident, is now melded to an AI. His enhanced senses have detected an alien artifact on Pluto’s surface, and he's not leaving without it.

Transferred to the research vessel studying Pluto, Randall and the other scientists are stumped as to the artifact's purpose and origin. Looking for similar signs of aliens they make their way to Pluto's moon, Charon, where, buried deep under its icy surface, something stirs—and wakes.

Against a backdrop of unknown alien technology and potential interplanetary war, Mikelson’s inhuman ego and obsession will risk humanity by calling something unknown to our solar system.

NOW IN MASS MARKET PAPERBACK:

Traveling to the stars will be difficult, but not, perhaps, the most difficult part. What about when we get to another star? What then? Will the planets be immediately habitable? Not likely. Will those who undertook the journey be able to easily turn around and come home if they don’t find “Earth 2.0?” Almost certainly not. Therein the lies the challenge: Finding worlds that are potentially habitable and then taking the time, perhaps centuries, to make them compatible with Earth life. They will encounter mysteries and unexpected challenges, but the human spirit will endure. Join this diverse group of science fiction writers and scientists as they take up the challenge of The Ross 248 Project.

First contact with the seemingly impossible human civilization at Proxima Centauri is not going well. The Earth ships sent to render aid have not been able to reverse the contagion ravaging their population and, worse, many Proximans are now wondering if the humans from Earth are there for other, not so charitable, reasons.

Can the extinction-level disaster faced at Proxima be reversed by the combined ingenuity of scientists from both worlds working together?

Unsettling discoveries in the Proxima Centauri planetary system beg the questions: What if the evil gods depicted in Proxima’s ancient mythologies were real and far more powerful than even the humans from Earth with their late 21st century technologies? Worse, what if their ancient oppressors never truly left?
