Like you and other normal, well-adjusted people, the author of this novella wanted to read a story about a Superhero with the ability to pass out glow-in-the-dark flatulence.
Since he couldn't find such a story, it was time to make one. This book tells the story of Greg Foster, the aforementioned Wind-Master (as he would prefer to be called), on his journey to recruit a team of Superheroes for a private investigation agency.
Backing him up is his boss, Ian. Quite frankly, even Ian knows Superheroes are unlikely to be useful to his agency, but hey, they provide a marketable gimmick.
And so, armed with the knowledge that his efforts will go far in the noble deed of providing the world absolutely nothing new of value, while still letting him profit off it, Greg sets out to recruit Bean, a highly paranoid and cowardly friend who can turn invisible (but only in front of people he feels comfortable around), and the other wacky characters that end up coming his way.
