...this confuses me. So...it's like tumblr...for books?
Either way, I'm mainly on Goodreads. I do occasionally come here, and also do periodically import my shelves from GR here, but GR is a more sure bet for contacting me.
THIS FIC IS AMAZING. THIS FIC IS AN EPIC. THIS FIC IS FREE.
GO READ IT. NOW.
This work is a goddamn epic. Okay, parts are kind of rough, but it has a great plot and imo decent characterization and good dramatic timing and such.
I don't even have words anymore. I'm all ranted out. Yeesh. But yeah, moral of the story is, go read this amazing epic, and then look into some of the author's other works. Xe writes 616, which I think is great.
(On a side note, this is also a great one:
It does magical things such as subvert the fanon Cap-is-technologically-illiterate trope AND doesn't overlook Captain Sassmaster. This one's shorter than the epic featured above, and is awesome fluff)
