Under a Winter Sun Worldburner Book 2

A Terran secret agent goes missing on the Goliath homeworld Nifelheim. Before he disappears, he manages to send out a message.

It simply reads "Project Jotun".

Nobody knows what it means, but all signs indicate the Goliaths are planning something. Something big. And they have help.

This scares the secretive immortal Terran overlords enough to request the aid of their old nemesis, Asher Perez, and propose a truce until the matter has been resolved.

It's not so much the mystery that convinces Perez to take the job. It's more that he will get to work very closely with a highly competent all-women special ops team.

And he will get to meet his old friend Thorfinn Wagner again.

Had he known what is about to hit the fan, he would have stayed home, stashed up on cheap whisky and drunk himself senseless in preparation for the end of the world.


Under a Winter Sun is the action packed sequel to Under a Dark Sky, and moves into more of a military science fiction pace, while still keeping the cyberpunk thriller elements and never straying far from the concepts of hard sci-fi.

Really, really good. Great pacing. A real page turner.

Under a Dark Sky Worldburner Book 1

A man who claims to be Christ reborn is executed and doesn't die.
A girl who knows way too much shows up out of nowhere.
A genocide that would make the god of the Old Testament curse his limited ambitions.

And that is just the beginning.

In the middle of this epic crapstorm stands world-weary security expert Asher Perez who only wants to enjoy his cheap whisky and even cheaper companions in peace.
Why can nothing ever be simple?


Under a Dark Sky is a hardboiled dystopian cyberpunk thriller, in the vein of Richard K. Morgan's Altered Carbon. Genetic engineering, all-powerful mega-corporations, hard-talking antiheroes and even harder women are the stuff of legends yet untold. They are also the backbone of the Worldburner universe.

Not my usual genre of fiction but I got to say I'm extremely impressed with Dahlgren's writing and looking forward to a sequel.
