Wow. Wow. Even if you aren't in the Mad Max fandom, you should read this fanfic.
Through connected short stories, eag explores the world and characters of Mad Max: Fury Road. Not just explore - eag builds them. The depth of these stories, the depth of these characters! I've read each of the parts... six? Ten? Maybe a dozen times and each read-through I learn more.
And damn, is there a lot to read. As of January 2016, the series is over 160,000 words. This is a tome-sized fanfic. And it's just as complex as well-written as any professional piece of fiction. If it were published in a book, I’d buy the hell out of it. I can’t rec this series hard enough. The complexity of the characters’ growth, and the joy of their triumphs and pain of their suffering gives them all such a pathos - Especially when you know their ultimate fate.
