Grace Brooks and Jack Carter are still trying to understand what happened to them-and why time seems to bend whenever strange science is involved. They promise each other that if they ever slip through time again, they'll face it together.
But time has other plans.
In a sudden flash, Grace is pulled forward-alone-into a future version of Miller's Island she barely recognizes. Familiar places feel wrong, technology hums beneath the surface, and Jack is nowhere to be found. Grace has already seen parts of this future once before, but living inside it is far more frightening than glimpsing it from afar.
As she searches for answers, Grace begins to uncover clues suggesting that her choices in the present may shape everything she's seeing now. And if she can't figure out what sent her forward-or how to get back-she may be trapped in a future that was never meant to exist.
Meanwhile, Jack is racing against the clock to bring her home, even as new questions arise about the science behind their time slips-and who might be watching their experiments from the shadows.
