I told you, Bill... something is wrong. I have sensed it for too long... something broken inside Mjolnir. And, for too long, I have tried to ignore it. To run from it. To cast it out of my mind. Today I will run no more. Today... I will face it. Mjolnir has grown heavier since I have taken the throne. And though I do not know how this is possible... I believe I know why. In my heart I know it is true. I have feared that I would soon be unable to lift Mjolnir. That somehow... it has grown tired of me... or that I have again become unworthy... but the truth... the truth is much worse... it is not only that I struggle to lift Mjolnir... it is also everyone else does not. 
Solicit Synopsis
SOMETHING IS WRONG WITH MJOLNIR! All-Father Thor needs his hammer now more than ever before…and yet the Uru grows heavier with each passing day. What will it take for the God of Thunder to hold on to one of the most powerful weapons in the Multiverse? Thor decides to reinvigorate himself by revisiting his old mortal persona after so many years, but he isn’t ready for the Donald Blake that awaits him—and neither is Asgard! As a trapped God of Thunder faces the Midgard Serpent, Jane Foster reckons with her former lover…reborn into reality and now a deadly enemy! With the fate of the Ten Realms in the balance, Thor must find a way to battle a crazed and determined Dr. Donald Blake—and when the hammer comes down, only one man will remain standing!
