Free Ebook: Northworld Trilogy by David Drake

Northworld Trilogy by David Drake is currently free to download from Amazon (US, ES). This is the product description:

The inhuman Rulers of the galaxy sent three fleets to learn what had happened to the world located by Captain North and the Survey Team he led. Neither a soul nor a message returned. The fourth time, the Rulers sent a single man: Nils Hansen.

Commissioner Hansen had a mind that saw the shortest path to each task's completion and a ruthless determination to do what the task required. The cost - to himself and whoever happened to be in the way - didn't matter. Hanson's Special Units had kept his planet safe from the most sophisticated and violent criminals in the galaxy. Now Hansen was being sent to penetrate a spacetime enigma which had made gods or demons of the first humans to discover it. He would succeed or die.

Northworld: a place of slashing violence and mystic transformation
Northworld: a place of treachery and dazzling beauty
Northworld: a place of honor, of faith, and of love.

Hansen's iron will and strong arm confront godlike power and godlike cunning while a galaxy trembles for the outcome. And if Hansen dies - he will not die alone!
