Four siblings reunite with an ancient sand-fairy and, aided by a mysterious amulet, undertake episodic journeys through time and legend. They visit lost cities, classical and Egyptian worlds, and remote islands, encountering historical figures, shipwrecks, and strange peoples while learning that wishes have unintended consequences. The chapters alternate domestic moments with vivid historical tableaux, examining curiosity, courage, and the responsibility that comes with magical power as the children’s playful adventures become instructive and occasionally perilous explorations of memory, myth, and imaginative possibility.
