I’m about to break one of the biggest rules of all.

But I need to find my dad. And if that means going back to New York City in 1998 to find him—before I’m even born—then that’s what I have to do. Because I need someone I trust to teach me what it means to be a Timekeeper.

Now I’m in the land of post-grunge, low-rise jeans, baby doll tees, chunky boots … and risking my own existence in the process. Awesome.

This is no ordinary trip. Just about anything can go wrong, and if I get found out, I’ll lose not only my home and school … but Braxton, too. Because there might not be enough forgiveness in the world for what I’ve done—and what I am about to do.

Because the secrets are more terrible than I thought. The reality is even more horrifying. And I’ll do whatever it takes to find out the truth about Gray Wolf Academy, the strange billionaire who runs it, and not only why he’s so invested in traveling—or “Tripping”—through time, but what his real plans are.

And time’s almost up.
