Three interlocking worlds. Four people looking for answers.

April, 1960: In the cellar of a professor's house in Oxford, fifteen-year-old Rosie goes in search of a missing cat -- and instead finds herself in a different world.

Anterwold is a sun-drenched land of storytellers and prophecies. But is this world real -- and what happens if Rosie decides to stay?

Meanwhile, a rebellious scientist is trying to prove that time does not even exist -- with potentially devastating consequences.

As the three worlds come together, one question arises: who controls the future -- or the past...?
