"Mom, are you sure the wolf will not come?" "Absolutely, my rabbit." "But how can you be so sure?" This clever story disarms childhood bedtime anxieties in an unexpected way. A small rabbit getting ready for bed questions his mother on how she can be so sure that the wolf will not come to their house. Meanwhile, on the opposite page, we follow the progress of the wolf indeed creeping closer and closer to them, foiling the mother's reassurances one by one. In a delightful twist, the rabbit's fears are defused and all ends well. The irresistible drawings and surprise ending put nighttime anxieties in light-hearted perspective.
