After the Battle of Hawkins, Eleven is displaced in a foreign land meanwhile Mike deals with the grief over the love of his life. As the pair enter the trails and triumph's of adulthood, three thousand miles away from each other, build new lives and careers, they both still think of each other often. Yet, are under the impression they will never see each other again. The angst and yearning for someone who can barely exist to you is a feeling unlike either of them have ever experienced. Bug the real question is, with the government still after El and Mike having no idea where she is, will they ever find their way back to each other? Or will they truly never see each other again?

Fall 1990, Mike Wheeler wrote books about the Hawkins events, telling everything that happened, even if people will never know it's true. He goes to Iceland, to a place with three waterfalls, like where he wanted to go live with El before her sacrifice. But some things will show him that everything isn't over, that there's still hope.
