Have you read the fanfiction the Wings of Wrath? It's a long one, but you might like it.
It's about Fang finding his reletives, and, well, thats the plot really, I don't want to spoil anything, but it's mostly just in-depth look at the relation ships between the characters.
(contains Fax)
Yeah..I havent read this one but alot of the ones I found were poorly set out or badly written. Some of them actually had a reasonable plot, but they were either rushed, had no detail, were made up of mainly dialogue that you had to try and figure out who was speaking or just plain not understandable.
I write, but...well, my writing style is probably terrible too x3
