Revenge of Metalhaven. Metal & Blood, #5

The rebellion has suffered a heart-breaking setback, but Finn Brasa remains determined to crush the Authority once and for all. To achieve that, he must reach Nimbus, the space citadel in orbit where President Gideon Alexander Reznikov maintains ultimate power and control. Unfortunately, Spacehaven is still under Authority control, and dozens of titanic rockets are preparing for a mass evacuation, taking the last of Earth's precious resources into orbit.
Once the last rocket has departed, Zavetgrad faces nuclear annihilation. Finn's fight is no longer to simply free the workers of Zavetgrad from oppression and servitude but to prevent the total obliteration of Earth's last survivors. For more than two centuries, the rulers of the Authority have been untouchable in their high tower, while millions suffered and died under their iron rule. Finn has already delivered justice to the people of Zavetgrad.
Now, he's out for revenge. Revenge of Metalhaven is book #5 of the Metal and Blood series, an exhilarating sci-fi adventure series packed with high-tech assassins, dangerous AIs, and daring rebellions. Join the fight for humanity's survival - start reading today!
