A most magical children's book, shortlisted for the Waterstones Children's Book Prize and illustrated by award-winning Chris Riddell.

Imogen should be nice to her little sister Marie. She should be nice to her mum's boyfriend too. And she certainly shouldn't follow a strange silver moth through a door in a tree. But then... who does what they're told?

Followed by Marie, Imogen finds herself falling into a magical kingdom where the two sisters are swept up in a thrilling race against time - helped by the spoiled prince of the kingdom, a dancing bear, a very grumpy hunter... and even the stars above them.

Thrilling, sharply funny, and with characters you will fall in love with, A Clock of Stars is a timeless fantasy from an astonishing new voice - and the beginning of an unforgettable journey...
