The only hope for mankind is Project Orpheus, an unprecedented initiative on the part of the allied governments to enable human life to continue on Kepler-442b, a planet over a thousand light years from Earth. Two spaceships are under construction, which will leave for that remote solar system with a specialized crew to terraform the planet and make it habitable. Steven Rhodes, the director of Project Orpheus, will travel in the first of them. His daughter Emily, a specialist technician in Artificial Intelligence, will follow on the second ship, five years later.

Accidents can lead to crazy circumstances, great discoveries, dangerous enemies, and maybe some new friends. What are the consequences of a scientist that opens a hole through space time? Or an exploration starship that is crippled as it dives into the gravity well of an unknown star system? It is the year 2293. An engineer, Tom Brown, opens a gateway through time. Another researcher in the Mesozoic, a Troödon dinosaur, opens a similar gateway. A stable link between them forms. That’s when things get interesting in both good and very bad ways.

Monsters don’t fear the dark. They fear him. Velik was changed by a childhood encounter he still struggles to understand. Now he’s something else—faster, deadlier, and armed with a unique class built for one thing: hunting monsters. For ten years, he’s braved the frontier alone, cutting down every beast that threatens the border towns. With each kill, he’s grown stronger, gaining levels and sharpening his skills on the thousands of monsters infesting the wild lands.

After flunking the entrance exam to his dream university, Temaru Ryūta is left behind by all his friends and becomes a shut-in while preparing for next year's exams. This is only the beginning of his bad luck, because one summer day he is inexplicably transported to another world, where people like himself are expected to become Adventurers.

As rebellion brews across the empire, from the golden streets of Carthage to the post-apocalyptic ruins of Earth, the machines set their sights on the ocean world Galapagos. But they face unexpected resistance from a fiercely independent population led by a battle-hardened submarine commander who refuses to surrender his world's freedom for the illusion of peace.
