Táto séria skúma tajomný svet, kde sa čas správa nepredvídateľne. Hlavní hrdinovia zistia, že existujú špeciálne okamihy, kedy je svet zmrazený a oni získajú nadľudské schopnosti. Ponorte sa do napínavého dobrodružstva, kde sa stretávajú osudy, objavujú skryté pravdy a bojuje sa o kontrolu nad samotným časom. Je to rozprávanie o dospievaní, priateľstve a objavovaní vlastnej sily v neobyčajných okolnostiach.
Upon moving to Bixby, Oklahoma, fifteen-year-old Jessica Day learns that she is one of a group of people who have special abilities that help them fight ancient creatures living in an hour hidden at midnight; creatures that seem determined to destroy Jess.
The Midnighters are unprepared for a new threat that stalks them in the daylight. This time, Jessica Day is not the only Midnighter in danger in this second volume of Westerfeld's mesmerizing trilogy.
The Midnighters have emerged victorious from their greatest challenge. They now know much more about the secret history of Bixby and, with the halfling dead, the Grayfoots' link to the darklings has been severed. But the cost is high. Rex's horrific experience in the desert has left him damaged, painfully suspended between light and dark. Melissa's violation of Dess's mind and the shameful revelations of her past deeds have shattered the uneasy bond among the five teenagers. What they need now is some time to heal, but what they get is the surprise of their lives when the blue time arrives in the middle of the day. It seems the walls between the secret hour and real time are crumbling, and soon the dark creatures will break through to hunt after centuries of waiting. And as if that wasn't enough for Jessica to deal with, her little sister, Beth, is becoming more and more determined to crack the secret of midnight - a goal that could have consequences more dire than she can ever have imagined.
