This is an electrifying thriller about the highly topical subject of people-smuggling, from one of the UK's leading children's authors.

Ellie has been scared of water since her mum drowned, so when her dad decides to move to a pub by a canal in East London, Ellie is afraid.

But she soon thinks there's something more disturbing about the pub than just its setting.

Something is going on at the weekly music night and Ellie and new friend, Flo are determined to find out what, despite warnings to back off.

The music night is clearly a smokescreen for something, but what?

Bundled from country to country on a harrowing journey from a tiny Chinese village with the false promise of a better life in England, Song Fang Yin knows the truth.

If she can escape her captors, she could help Ellie expose it.
