Knowing Chris Bennett's Writing as I do, I expected Only Superhuman to have an imaginative plot and a compelling superheroine in Emry Blair. What I hadn't expected was for the backstory to make so much sense. Usually science is the first causality of superhero stories, tossed aside with the breezy rationalization: 'Hey, it's comics!' Only Superhuman is, to my knowledge, the first hard science superhero story. And the Story is the better for it.
