So I picked up Urban Enemies (edited by Joseph Nassise) mainly because Kevin Hearne advertised that it contained "The Naughtiest Cherub", which tells the story of Loki meeting Lucifer. (I should mention: the gimmick here is that all the stories in here are told from the point of view of the antagonists of their various series.)
There are other authors and other series in here that I read, so they were a sort of bonus.
We start off strong with Jim Butcher's "Even Hand", told from Marcone's perspective, as he's forced to enforce his part of the Accords. I suppose Marcone is a villain, but the Dresden files is filled with other complex antagonists who would be more qualified as villains. Not that it matters, it mostly has to do with Marcone mediating a rather violent dispute between some Formori and the local White Court of vampires. Using bombs.
"Sixty Six Seconds" by Craig Schaffer (I'm skipping a few here, since a few of the stories weren't particularly of interest to me, so I'm doing highlights) Crosses his Daniel Faust series with his Harmony Black series. It mainly concerns demons collecting bounties on souls. It reads a bit like Simon R. Green, without the cheekiness.
"The Naughtiest Cherub" by Kevin Hearne continues my love/hate of the Iron Druid. I mean, while giving Lucifer quirks of liking Prince and David Bowie, his portrayal of Loki continues to disappoint.
"Down Where the Darkness Dwells" by Joseph Nassise is ok, dealing with a necromancer who manages to form a symbiotic relationship with Asheral, a fallen angel.
"Bellum Romanum" by Carrie Vaughn deals with the origins of the vampire Gauis Albinus who is somehow responsible for Pompeii.
"Make It Snappy" by Faith Hunter concerns the Master Vampire of New Orleans and his brother.
"The Difference Between Deceit and Delusion" by Domino Finn follows Tunji Malu, some kind of African demon who eats people. He also has a very charming tarantula the size of a small car named Ananasi.
"Balance" by Seanan McGuire explains much of the history of the Jhorlac (aka Cuckoos) and how they operate.
There are other stories and authors in here, but these were the ones that actually stuck out to me and made me want to see if the library has their series. Mind you, what it really served to do was make me wish Jim Butcher would write another Dresden File....
