Superhero fiction is a niche genre in a niche genre. Superheroes thrive in comic books, video games, and movies but aren't so very popular in prose fiction. Perhaps because it's such a visual medium but I think it's more there's just never been an iconic example of the genre. Despite this, there's some truly great examples of superhero fiction which I've been proud to review. Things like Wearing the Cape, Origins of a D-List Supervillain, Soon I Will Be Invincible, and Villains Rule.
BROKEN NIGHTS opens with a pair of petty crooks breaking into a store in order to steal a bunch of iphones when they're confronted by a shadowy cowled figure. They jump across a pair of rooftops when the figure jumps to catch them and misses the roof before smashing into the ground a couple of stories below. Wannabe Batman, Jason Night, does not begin his career in an auspicious manner.
