The Final Hour of Prometheus

It is a fantasy/dystopian book about superheroes, on the cover I want the main character (Prometheus/Tim Saylor: he is an 18-year-old with vibrant orange eyes, and brown dusty hair, and his hair will sometimes light on fire when he uses his powers but he's completely fireproof, he wears an old dusty brown coat jacket and a mask that his sister made for him when she was in a university for college) I want him to be hanging from the ceiling held by invisible strings (Like a Puppet) but a few are seen by the glint of the light, there is a pattern behind him in the background that is black and purple, also there is a title card above it IRIS: New Order, it is covering who is controlling the strings (Like the Puppet Master)
