Winner of the British Book Awards’ Children’s Book of Year 2017

Forbidden to leave her island, Isabella Riosse dreams of the faraway lands her father once mapped.

When her closest friend disappears into the island’s Forgotten Territories, she volunteers to guide the search. As a cartographer’s daughter, she’s equipped with elaborate ink maps and knowledge of the stars, and is eager to navigate the island’s forgotten heart.

But the world beyond the walls is a monster-filled wasteland – and beneath the dry rivers and smoking mountains, a legendary fire demon is stirring from its sleep. Soon, following her map, her heart and an ancient myth, Isabella discovers the true end of her journey: to save the island itself.
