Seraph Falling

They erected the walls to keep out humans.
Patches never wished to be a hero, not like in comic books. His dream of being forgettable ended when he received a note written by a dead psychic fifty years ago. Cursing her name, he travelled to the Tower. He had heard rumors, but didn't expect a technologically advanced sanctuary for the Children of Nostradamus.
For Eve, becoming a hero was her only ambition. Despite lackluster powers, she demanded to be like her fathers, retired superheroes who once saved the world. A rejection letter from the Sentinel's peacekeeping program crushed her hopes.
The true threat lives within their walls.
When an unknown saboteur lowers the Tower's defenses, a wave of synthetic killing machines set out to dismantle their utopia. An unsuspecting Patches is at the center of the mystery. Eve sets out to discover why, even if it results in being banished. But to save their home, they'll need to confront a menace more powerful than they could predict. Unlike the comic books, death is permanent and without them, the Tower will collapse.

Jeremy Flagg expands the Children of Nostradamus Universe in Sentinel Rising. This stand-alone series introduces new superhero characters in a dystopian cyberpunk setting.
