It's a snowy winter's night in the city. The bedroom lights are off and it's time to settle down to sleep. But wait! What's that? Strange and scary sounds are coming from the streets outside. What can be making these sounds? Are monsters coming? Don't worry! Through rhyming text and atmospheric artwork, young readers can first imagine what might be making these mysterious sounds. This clever concept is based on a bedtime ritual the author used with her own grandchildren to assuage their nighttime fears.
