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 exciting sequel to Under a Dark Sky, and moves into more of a military SF pace, while still keeping the cyberpunk thriller elements and never straying far from the concepts of hard sci-fi.
