Any fans of Worm (by Wildbow) on this forum?https://parahumans.wordpress.com
Its a very excellent web serial. Initially looks like a teen drama, turns into Game of Thrones with superpowers.
Yes, I've read the aSoIaF books, and yes, the amount of plots stack up. In fact... There are actually some pretty good parallels between the White Walkers and the final antagonist of Worm.
And unlikely aSoIaF, this series is actually finished. Well... Sorta.
