This book offers readers a chance to jump back in time and explore three stories about Anna Fang's journey before meeting Tom and Hester. The illustrations in this book suggest that it is geared toward a younger audience, but the themes it explores are more adult in nature. This book showcases the power of Anna's character, as well as locations that are less familiar to readers. The stories highlight the difficult conversations about power and privilege that readers of the original quartet will recognize. Philip Reeve's writing creates a brilliant science fiction experience, making this small entry a wonderful way to experience the roving cities and their adventures.
