Meg knows she’ll start sixth grade at a new school, but then a letter arrives and changes everything.

It’s an invitation to participate in the TILT time exchange program, an exclusive chance to travel into the future. But accepting the opportunity means taking on a daring challenge. Every traveler is assigned a token, and to return home, they must correctly figure out its purpose.

Meg discovers that she needs much more than a tether and a token to make it in the future—and make her way back home. She needs curiosity and a willingness to mess up, too.
