Guardians of Time

What if you entered a world full of magic and mystery—but couldn’t get back home? When Sybil, her kid sister Alex, and two cousins discover a magical book in the family manor, it opens a hidden door into the forest of Keoherus. As the powerful Warriors Four, the girls must now locate secret temples and solve intricate puzzles to gather crystals that will allow them to control time. But when Alex is captured by an evil force, they must rescue her and find a way home—or stay trapped in Keoherus forever.
