This is such a sweet story. A child is woken from sleep in the middle of the night by a father who promises to show her the titular "pieces of another world." The child sees her own world at night for the first time, both her urban world (empty grocery store, busy all-night restaurant) and her natural world (nocturnal wildlife). Finally, she sees the promised other worlds, which you and I knew all along were meteors, but which may be a surprise to young kids being read this story. This book would be a super way to prepare kids for their first trip with you to watch a meteor shower.
