And we won't even have to wait that long to get our hands on the books! The first two will be available this year, with even more to come afterwards. The first two will be BTS companion books called Stranger Things: World Turned Upside Down: The Official Behind-The-Scenes Companion, as well as a hardcover book designed for young adults.
The next book will be full of mystery, and the title has yet to be announced.
Although, the published has promised it will contain “advice, wisdom, and warnings from the Stranger Things world.”
The prequel novel will be based on Eleven's mother who was part of the MKUltra program, which we can assume will show us how Eleven/Jane came about with her super powers.
