The Rosewater Redemption (The Wormwood Trilogy #3)

Life in the newly independent city-state of Rosewater isn't everything its citizens were expecting.
The Mayor finds that debts incurred during the insurrection are coming back to haunt him. Nigeria isn't willing to let Rosewater go without a fight. And the city's alien inhabitants are threatening mass murder for their own sinister ends...
Operating across spacetime, the xenosphere, and international borders, it is up to a small group of hackers and criminals to prevent the extra-terrestrial advance. The fugitive known as Bicycle Girl, Kaaro, and his former handler Femi may be humanity's last line of defense.
