It's a graphic novel about stories and how they impact the real world. I mean, one of the lines is "Stories are the only thing worth dying for", and at that point it becomes rather hard for me to be objective, even without the Kipling/Wilde/Twain cameo.
It's interesting, it's smart, it's original as hell
. It's clearly setting up for more developments, both in terms of plot and in terms of the world.
The protagonist's name is Tommy Taylor, both in the story and in the story-the-story's-about. He's a man who (rather unhappily) makes a living off the fact that he's identified with/as the young wizardly protagonist of the books his father wrote... sort of as if Rowlings had mysteriously vanished and her son Harry Potter had grown up as the target of a lot the fannish devotion. He's working the convention circuit when a young woman stands up during Q&A and asks him who he is, since pictures taken in his early childhood are actually pictures of someone else, and his SIN appears to belong to a woman who died a while ago, and...
Things develop from there.
I hesitated a bit before putting the "horror" tag on the book, but decided in favour of it. It's slightly distant--horror does show up, but it seems to more often be something the story is about than something that's happening in the story. Still, I think it counts.
