My first impression was that the editing is... rough. I mentioned this to the author (we're connected on Google+), and he said that he and a couple of editors had gone over it but something always gets missed. Well, they missed quite a lot, actually. Mostly typos, misplaced commas, quotation marks closed in the wrong place and so forth, but several clangers as well. Blake: The piece of gymnastic equipment is called a pommel horse, not a pummel horse. The Happy Days character was Ralph Malph, not Ralph Mouth. And a split between members of a group is a schism, not a chiasm.
Apart from that - and as a former editor, these things annoy me disproportionately - I loved this. I'm a big fan of superhero novels, though I've at least temporarily given up on the comics because the way the women are drawn isn't good for my head. (The final trigger was a collection of Legion of Superheroes. I looked at Objectified Girl and Inadequate Clothing Lass, or whatever their names are, on the cover and decided to return it to the library unread.)
Other People's Heroes, though (which is what I was talking about, in case you also had forgotten), had all of the strengths of a really good superhero tale, without the silliness.
It wasn't predictable - at least, only one of the three things I thought would happen actually happened. The central character was a decent guy doing his best with the hand he'd been dealt, which is my favourite kind of protagonist. There was enough action to be exciting without it being wall-to-wall fisticuffs, a good balance of conflict and reflection. And the superhero powers were a mix of classic and fresh. There were nods, for comics fans, to a lot of DC and Marvel heroes, but it managed to be a tribute rather than a rip-off. (Particularly since these were the minor characters - all the majors were original.)
When I finished, I went to the Kindle store under the vague impression that I'd seen another novel in the same setting, but it turned out to all be short stories. Please, Sir, can I have some more?
