'This book is stunning – Zohra Nabi writes like a dream and has achieved the impossible by conjuring up a living, breathing Victorian London right before my eyes. I felt like I was right there with Cassia while reading it, magic sparkling around us.' – Natasha Hastings, author of The Miraculous Sweetmakers

The dark was deep; it opened like a cavernous mouth and swallowed the boy whole.

Cassia Thorne leads a double life. By day, she sells ballads at Bartholomew Fair. By night she spends her evenings locked up in Fleet Prison. Cassia has plans of escaping both of these lives. But this year there are rumours of children being snatched off of the streets of London and no one willing to help.

So Cassia decides to take matters into her own hands; with the help of a young pickpocket, Teo and her friend Felix, Cassia starts to investigate the disappearances. She soon discovers a sinister conspiracy at the heart of the city - mysterious men in blue coats and whispers of a beast that lives in the deep dark tunnels below the city. Can Cassia get to the bottom of the mystery and rescue the missing children before it's too late?

Join Cassia and her friends on a spine-tingling supernatural adventure through the streets of London!

A breathtaking new direction from a rising star and the author of The Kingdom Over the Sea, a Waterstone's Children's Book of month.
