The Dresden Files/Small Favor

Book #10 in The Dresden Files.

No one's tried to kill Harry Dresden for almost an entire year, and his life finally seems to be calming down. For once, the future looks fairly bright. But the past casts one hell of a long shadow.

An old bargain has placed Harry in debt to Mab, monarch of the Winter Court of the Sidhe, the Queen of Air and Darkness-and she's calling in her marker. It's a small favor he can't refuse...one that will trap Harry Dresden between a nightmarish foe and an equally deadly ally, and one that will strain his skills- and loyalties-to their very limits.

It figures. Everything was going too well to last...

Tropes associated with Small Favor:

 * Always a Bigger Fish:
 * Armor Piercing Question:
 * Back to Back Badasses:Harry and Michael.

 * Chekhov's Gun: Inverted, when the absence of any mention of  becomes a significant plot point later, when
 * CPR Clean Pretty Reliable: Averted when Dresden apparently spits up fishy aquarium water during the process.
 * Demonic Possession: The Knights of the Blackened Denarius act as hosts for the Fallen.
 * Eternal Love: Nicodemus Archleone and Polonius Lartessa, although their relationship may be a warped version of this trope.
 * Eye Scream: Mab found what is probably the only way to get Harry to stop making smartass comments. It was not pretty.
 * Gatling Good: Hendricks, to the tune of The Ride Of The Valkyries.
 * Get It Over With: When Harry defeats the gruff at Union Station, it tells him to finish it. Twice. Whereupon Harry says he does not kill unless necessary, much to the shock of the gruff, who had assumed he was actually in Winter Court.
 * Hannibal Has a Point: As truly terrible a person as he is, even Harry finds it hard to argue against Nicodemus when he talks about how the Black Council are disrupting things and causing trouble for everyone, or when he talks about how the Red Court needs to be destroyed.
 * Hope Spot: A particularly devastating example occurs for Michael of all people in Small Favor. After the battle in the aquarium that resulted in the deaths of several Denarians, with their coins being subsequently collected, Michael realizes that combined with the other Denarians that they know are in the area, along with the Denarians who have already been defeated and their coins collected he, Harry and the others are within a hair's breadth of defeating the entire order of Denarians and putting an end to their war with the Church once and for all. Unfortunately,  And that's not even counting what happens to Michael himself.
 * It Was a Gift: after Harry talks with Jake (who is the janitor -- really), Jake vanishes, leaving behind a copy of The Two Towers, which opens on some — interesting passages.

 * Mundane Wish: Subverted, when Harry "wastes" his single wish, which could make the entire Summer Court of Faerie do whatever he wants of them, on a doughnut.
 * My Master Right or Wrong: The Gruffs really do not want to kill Harry, but are loyal to Court and Queen. (Fortunately, in that order.)
 * Offhand Backhand: Ivy pulls off one of these,
 * Screw Destiny: Harry notices that Gard was staring at Michael in a foreshadowy way and decides to alter his actions to prevent what he thinks is coming..
 * Sand in My Eyes
 * Snowball Fight: The beginning of Small Favor has one involving the entire Carpenter family and Harry.
 * Telepathic Sprinklers: Averted, since Harry did it. Specifically, since all the sprinkler heads are the same he used thaumaturgy to heat them all up at once.
 * Touched By Vorlons: Harry gains  thanks to.
 * Training From Hell: Harry uses a family snowball fight at the Carpenter house to teach Molly how to create a defensive shield. Charity comments on this and Harry remarks that it's good training. Charity asks if that's how Harry was trained and Harry replies that Justin used baseballs.
 * Unreliable Narrator: Harry's usually pretty straight with the readers, but on this occasion it's played with when he leaves out a minor, but significant event in the plot . Also used as a handwave for inconsistencies from early in the series, such as one minor character whose name changes in between books (Harry heard it wrong the first time), or when Butcher gave Wrigley Field a parking lot that it doesn't have in real life.
 * Unstoppable Rage: Harry unleashes Pyrofuego in a beam of destruction that blasts
 * A little before this, the Denarians attempt to turn Harry's Unstoppable Rage against him by  Fortunately,
 * Xanatos Speed Chess: The Denarians play a mean game. Harry and Michael note on several occasions that the Denarians seem to plan things out so that no matter what happens they can still come away with some advantage. Fortunately, in Small Favor Harry proves that he is also becoming quite an adept player of Xanatos Speed Chess and manages to play the Denarians to a draw at the end of the book.
 * You Are Not Alone
