After ten years of living on an isolated, tech-free ranch with her mother, sixteen-year-old Hedda is going back to the world of the Glare–her word for cell phones, computers, and tablets. Hedda was taught to be afraid of technology, afraid that it would get inside her mind and hurt her. But now she’s going to stay with her dad in California, where she was born, and she’s finally ready to be normal. She’s not going to go “off-kilter,” like her mom says she did when she was just a little kid.

Once she arrives, Hedda finally feels like she’s in control. She reunites with old friends and connects with her stepmom and half-brother. Never mind the terrifying nightmares and visions that start trickling back–they’re not real.

Then Hedda rediscovers the Glare–the real Glare, a first-person shooter game from the dark web that scared her when she was younger. They say if you die thirteen times on level thirteen, you die in real life. But as Hedda starts playing the so-called “death game”–and the game begins spreading among her friends–she realizes the truth behind her nightmares is even more twisted than she could have imagined. And in order to stop the Glare, she’ll have to first confront the darkness within herself.
