A new darkness stirs beneath Hawkins, older, angrier, and far from finished. When strange visions begin haunting Will Byers again, the past he thought he escaped starts pulling him back toward something he can't explain. Shadows twist where they shouldn't. Memories blur into nightmares. And something in the air feels wrong... like the Upside Down is breathing again. As the threat grows stronger, the people Will trusts most begin to sense it too. The world is shifting. The rules are changing. And something, or someone, is coming for him. But Will isn't the only one keeping secrets. A hidden force is moving in the dark, watching, waiting, preparing for the moment everything breaks. When the truth finally hits, it will shatter everything the group thought they knew about the past... and about each other. Because this time, the fight isn't just for Hawkins. It's for the one person the darkness refuses to let go
