Moving to the quiet, dusty town of Bixby, Oklahoma, is the last thing Jessica Day wants to do. She expects her new life to be incredibly boring, but everything changes just a few nights after she arrives. Jessica wakes up exactly at midnight to discover that the entire world outside her window has completely frozen. Raindrops hang suspended in midair, and her family is paralyzed in their beds. Jessica soon learns she is one of a rare group of teenagers known as Midnighters. They possess extraordinary abilities and are the only people who can consciously experience this hidden, extra hour of the day. But the secret hour is far from safe. The frozen shadows are inhabited by ancient, terrifying creatures that despise humans. For some reason, these dark monsters have taken a very specific and violent interest in Jessica. To survive the night, she must quickly master her new reality and uncover the town's darkest secrets before the creatures hunt her down.
