In crime-ridden Crystal City, superhumans are being manufactured.
After Bryan Whittaker survives a personal tragedy, he decides to help save the city from the forces that killed his family. Signing up for the Hero Program, Bryan becomes Soulfire.
Years later, the products of the program are targeted by an assassin. Soulfire finds himself being accused; he’s the only one strong enough to overpower the others. But is there someone else in the game?
With the corrupt Hero Factory shaken to its foundations and the future of the city hanging in the balance, Soulfire must find the real killer and bring him to justice.
One must find out why one is born, and Bryan Whittaker was born to be The Last Hero.
