In 2016 an occult cabal activates a psychic trigger in a popular video game and a countdown to chaos begins.

While her husband is deployed in Afghanistan, Jessica Ritter finds herself navigating the pitfalls of parenting on her own. That includes moderating her ten-year-old son's screen time—an obsession that hits a fever pitch when YouTube sensation Rainbow Dave releases an addictive new iPad game. Gavin knows he isn't supposed to keep secrets from his parents, but when his achievements in the game unlock personal messages from Dave instructing him to embark on real world mini-quests, he can't resist.

In the aftermath of an ambush that leaves her husband missing in action, Jessica grapples with fear and sorrow while clues to a threat closer to home evade her detection. Rainbow Dave, the charismatic host of Scream Time, is America's cool big brother—a gamer who built a video empire on the strength of his personality. He is also the focus of a shadowy conspiracy hell-bent on sowing chaos with vast technological resources. Dave's anonymous benefactors have granted him a glimpse of paradise between the pixels, and the real world hasn't looked the same since. Now, wired with a head full of unholy revelations and a crate full of dangerous devices, he's on a mission to help his fans "level up" at a live event. Scream Time is coming to town, and it may be too late to stop a deadly game.

"An expertly-written mainstream thriller, tightly plotted, with beautifully human characters and a chilling touch of the supernatural. His Own Devices is full of suspense and just the right amount of weird. The menace couldn't be more timely."

–Christopher Golden, New York Times bestselling author of Red Hands
