In 1939 Siegel City only had one superhero, the world's first. When he discovered his powers, Gabriel Ruston thought he would be the second, but died on his first excursion in costume.
After Gabriel's death, his brother David is drawn into an investigation. What if Gabriel wasn't the second? What if there were others? What if something tragic happened to all of them?
In Siegel City, nothing is ever what it seems... even in a Golden Age.
