26 parts Complete The hardest words weren't "I love you"-they were "I promise."
Mike Wheeler never thought he'd have to choose between keeping his life and keeping his word. Yet now, trapped in the terrifying reality of the Upside Down, survival is a countdown. With every step taken alongside a mysterious stranger who seems to know how to fight the impossible, Mike feels his mind fraying under Vecna's influence.
He has to get back. Not just to his friends, but to Eleven, who is fighting her own battle thousands of miles away. Mike realises that the only thing stronger than the monsters trying to tear the world apart is the promise he never got to keep.
To survive, Mike must become the leader he never knew he could be, because if he fails, he won't just lose his life-he'll lose her forever.
