So far, the Sandman Slim books have been non-stop, rollicking fun. Our (anti)hero, Stark, just wants to be left alone and he'll kill anything that gets in the way of that, which keeps him picking up strays to care for and responsibilities to maintain at a disturbing rate. As of this short story, listed as volume "3.5" in the books, he's taken over the title of Lucifer and trying to keep hell from boiling over into rebellions that could affect the mortal world. After all, the mortal world is where he keeps his stuff. And his favorite bar. And the vampire-thing he's kind of dating. And the video rental store he stole.
You see how it is. A short story about him proving he's as tough as they say would come in handy right about now.
But it's barely a three-out-of-five, sadly, for two reasons.
First, setup isn't strong. It isn't clear if the story is intended to be only for readers familiar with book 3, but there are too many throwaway characters and too many lines explaining what someone who's read along so far already knows and somone jumping in at this story probably won't understand anyway.
The action is fine (and actually understated, for the series), and we get some great bits from Stark about why he's immune to the various psychological harrassment that does in the Hellions around him, but the mythology behind it, and the motivation for him to be involved at all, aren't handled as well as we know Kadrey can do in a longer form. It feels like the various mythology sections of book 3 pared down to a few dozen lines, which just doesn't work well.
But it's the second flaw that really hurts the story: It just doesn't matter. I mean, it really doesn't matter. At the end of the story, it might as well not have happened. We get some fun along the way, but it has one of those auctorial cop-outs that make a story basically a writing exercise. Story, but no plot.
It is possible, of course, that Kadrey intends to reference this story somewhere later, and it's possible that the cop-out is an important plot element. I hope so. It would be great. But even then, there would be ways to write the story (or maybe times to release the story) that wouldn't leave the reader feeling as cheated.
If you read the series, and if you're continuing after book 3, go ahead and spend the $0.99 to get this and enjoy it. But try to have the next book handy for when you realize it wasn't what you wanted.
