This is a story about time – which can go quickly or stand still. And get lost. Best friends Yesper and Noper go to bed after a long, busy day. They’re keen to get some rest. But when they wake up again at last, they find they’ve slept for ten whole years. What’s happened to all that time? Have they lost it? Can the Thief have stolen it? Can they buy some time from Slowper at the corner shop, who always has all the time in the world? Or could a time machine be their salvation?
