Summary: The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one state into another. And what is grace, if not energy? In order to win the war in Heaven, Castiel and the Winchesters embark on a cross-country quest to find the scattered shards of Gabriel’s grace in the hopes that its remaining power will be enough to defeat Raphael before he and Crowley can open the door to Purgatory.
Why You Should Read This: Because if I were to rewrite season 6, this is what I would have done. Essentially, Castiel turns away from the path he was going down and risks his very existence for a chance at becoming powerful enough to defeat Raphael. Over the course of the journey he, Dean and Sam undertake, Castiel and Dean confront their feelings for each other. Some moments are just heart breaking, while others are frightening and others are enough to make me laugh. The ending is fantastic and well worth the emotional journey. This was a BigBang fic that was giving the star treatment by the fantastic artist artmetica.
