Guide Me Home

Guide Me Home is an Avatar: The Last Airbender Fanfic written by Qwi-Xux that has gained popularity in the fandom for... actually being good.

Essentially, it's an What Happened To All Those Mice, Hurt/Comfort Fic that follows Princess Ursa during all three books and is completely Canon compliant. Ursa has been living in the Earth Kingdom and secretly helping La Résistance. When she discovers a Fire Nation spy amongst the Earth Kingdom underground, she is forced to flee and is rescued by Chief Hakoda and his crew.

Ursa and the crew (especially Hakoda) eventually grow closer. Of course, they don't know she's Fire Nation...

It can be found here.

Tropes used in Guide Me Home include:

Arranged Marriage: Ursa and Ozai. It Got Worse.
- There is also a nameless Northern Water Tribe couple who get married. That one could possibly be a Perfectly Arranged Marriage. They are "very much in love".
Badass Crew: The Southern Water Tribe warriors.
Bittersweet Ending: The war is over, Hakoda and Ursa are together and Zuko has a mother again... but Azula is damaged almost beyond repair.
Blazing Inferno Hellfire Sauce: Ursa cooks a Fire Nation dish for the crew. In her defense, she did warn them.
Broken Bird: Ursa, at first.
- Azula, even more so.
Domestic Abuser: Like anyone needed another reason to hate Ozai.
Deadpan Snarker: It's a Water Tribe tradition apparently... but Mai's only line in the entire fic cements her position as Avatar's quintessential Deadpan Snarker.
Defrosting Ice Queen: Ursa, sometimes. She has a tendency to shut off her emotions when she feels that showing them would make her vulnerable.
Early-Bird Cameo: Toph.
Everyone Can See It: "I don't know who you two think you're kidding... but it's sure not us."
Elsewhere Fic
Flashback Nightmare: Ursa has many... to the point where she actually finds it "refreshing" to have a normal nightmare.
Flat What: Qwi-Xux manages to turn this trope into a Tear Jerker.

Hakoda: With outside help from my son... and yours.
Ursa: What?

Foregone Conclusion: Ursa goes to Ba Sing Se to find Zuko and Azula and get them to end the occupation. That'll work.
Groin Attack: While teaching Ursa how to fight, Hakoda pins her against the wall and accidently puts his hand over her scar. She panics, a Groin Attack ensues and Ursa is absolutely mortified afterwards. Yes, that is an actual Tear Jerker example of this trope.
Happily Married: Mikko.
Heroic BSOD: Ursa has one when she finds Zuko's wanted poster...and sees his scar.
Heroic Self-Deprecation: Ursa is filled with guilt and shame at the start of the fic despite her work for the underground.
It's Personal: After Hakoda finds out that Ursa was married to Ozai, the war becomes even more personal for him.
Killed Off for Real: Poor Ornu.
La Résistance: Ursa is part of one at the beginning, and it seems that the Order of the White Lotus fills this role more than it did in the cartoon.
Mama Bear: Guess.
Mommy Issues: Katara and Azula in spades. They're getting better.
Mundane Utility: At one point, Ran uses is firebending to make toast for The Duke.
The Power of Trust: How Ursa finally gets through to Azula.
Papa Wolf: Hakoda. The phrase Papa Polar Bear is actually used to descibe him.
Rescue Romance
Single Woman Seeks Good Man
Took a Level in Badass: Ursa.
Torture Always Works: Averted. The red spider-fly venom is nasty but unreliable.
There Is Only One Bed: Hakoda offers Ursa his blanket, claiming to be used to the cold. Ursa decides to take a third option and they end up sharing.
The Mole: Lots, of course, since this story is about an underground spy network. Special mention goes to Ran, an Order initiate operating from within the Fire Navy who helps Ursa and Hakoda escape from Zhao.
"The Reason You Suck" Speech: Ursa delivers one to Ozai. At this point the readers are cheering for her.
Talking the Monster to Death: Ursa to Azula.
What Happened to the Mouse?: This fic seems to exist to explain what happened to the mice, including Ursa, of course, Hakoda at various points, and also Longshot, Smellerbee, everyone else who split up from the Gaang at the beginning of "The Southern Raiders", and a few other people who showed up once and never appeared again.
