From the #1 bestselling author of RESTART, the story of five kids who are up all night every night... and desperate to find out why.

There's not enough time in the day.

How often have Mickey, Skye, Levi, Cyrus, and Thea thought that?

Well, now they have plenty of extra time... because they no longer need to sleep.

None of them know why this is happening to them. All they know is that they have to keep it a secret from their families and their friends. And while they keep it a secret, they can use their extra hours to become better than everyone else.

Each of them thinks they're alone in their sleeplessness. But once they find each other, they know it can't be just an accident. Suddenly they're forced to ask:

What's keeping them awake at night?
