Alice Hopper knows exactly what it means to be a ghost. She has been haunting her own father's life ever since her twin sister, Sara, died of cancer seven years ago. While Jim Hopper drowned his grief in alcohol and apathy, Alice perfected the art of being the "good daughter"-getting good grades, smiling for the neighbors, and staying out of trouble, desperate to prove that she is still here. That she still matters. But "perfect" doesn't work in a town like Hawkins. When Will Byers vanishes into thin air and her best friend Barb disappears during a party at Steve Harrington's, Alice realizes that following the rules won't save anyone. Desperate for answers her father refuses to give, Alice forms an unlikely alliance with the town outcast, Jonathan Byers. Together, they pull at the loose threads of a quiet town, unraveling a conspiracy that leads them to a girl with a shaved head, a government lab with too many secrets, and a terrifying world beneath their feet. Alice is about to go down the rabbit hole, but this isn't Wonderland-and she might not make it back out.
