Ever since his father’s disappearance, teenaged Darius has made a living for himself as a small-time con artist, cheating tourists out of their money on the hot streets of Memphis. When a mysterious woman starts following him, he thinks the police are finally on to him—but the truth is far stranger than that. Darius has been recruited by Project Oberon, a top-secret government organization dedicated to preventing disasters—before they occur. Oberon has created a portal that allows people to go back in time, to exactly twenty-four hours earlier.

Then disaster strikes New York City, and Darius and his team of special ops teenagers are in the Portal, heading back with just one day to prevent the unthinkable. But it soon becomes clear that this villain is unlike any they’ve ever faced before—and knows far too much about Project Oberon.

Can Darius and the team save the world before their twenty-four hours are up, or will they be lost in time forever?
