When you are afraid to fall asleep, when all your dreams are nightmares, write us a letter, put it under your pillow, we will rescue you. . . .

It is almost time for the old and tired Sleepwalkers to return to the waking world. But before they go, they must conjure and train three new replacements. Who else will look after the Sleepwalking House and be there to answer the call of a child frozen with fear, trapped in a nightmare? Faced with a series of cliff-hanging dream predicaments, the three brave new heroes tackle the weird and the wild in this tale about pulling together as a team and having the confidence to stand up to your fears.
