Have you ever imagined what you would find if you were able to go inside one of those magnificent sand sculptures that you see at the seaside? Jamie, his sister Clare and his friend Ben did just that. They enter a secret tunnel at the back of a sandcastle that leads them to the Sandlands, a mysterious world where everything and everybody is made of sand. They discover a time glass inscribed, "THE SANDS OF TIME RULE THIS KINGDOM." When Clare and the time glass are taken by pirates they immediately find themselves in a perilous race against time. Disaster strikes, putting their lives in great danger. Will they rescue Clare and retrieve the time glass before it's too late? Will they escape from the Sandlands alive? Only the Sands of Time will tell.
