A secret time portal. A desperate cry for help. Can a young girl change her own future and save the world from a terrifying fate?

All Clara wants is to fit in and make friends at her new school, but when she discovers a time portal within an overgrown mine shaft, her life is turned upside-down.

Following an urgent cry for help from the future, she is charged with a crucial mission: stop the evil Derek Maunding from stealing the mine’s secrets. If she fails, it spells disaster for the world.

Moving between future and present, Clara and her new friends race against the clock to rescue the mine and safeguard its hidden time portal. Putting their lives—and their futures—at risk, they must battle dangerous enemies, including Maunding’s bullying daughters, who will stop at nothing to help their father achieve his aims.

The fate of the world rests on Clara’s shoulders. She must outwit those who seek to control time—even if she pays with her life.
