*Sigh* Romance is in the air in the Avatar world. I've done you die-hard shippers a favor and listed stories by 'Ship. (That's relationship, for those of you unfamiliar with the lingo!)
For those who loves to write about Zuko and Katara as a couple
"The Ho'Wan Island Carnival" by Vicki So (T) What happens when Aang, Sokka and Katara spend a day in the greatest year round carnival on Aang's birthday? How will Prince Zuko deal with trying to act like a normal teen while still hot on the Avatar's heels? Zutara, Comedy, Angst, and more!
Deathly by Vicki So (K+) Zuko and Katara's thoughts in the hours following their departure from The Ho'Wan Island Carnival, to the tune of Deathly by Aimee Mann. One shot.
"Bent" by Vicki So (T) The trio and the Prince have a run in on a strange island that strips benders of their powers... and their lives. What mystery does the island hold? Zutara, with a little bit of everything, even Momo! Sequel to The Ho'Wan Island Carnival. COMPLETE!
"Best of Breed" by Vicki So (K+) A horse is a horse, of course, of course, and no one can talk to a horse of course, that is, of course, unless the horse is... a banished Fire Nation Prince? Darn those rabid plot bunnies! Zutara.
