Winner of the Costa Children's Book Award 2011 Every step of Saba's journey sizzles with danger...

In a lawless land, where life is cheap and survival is hard, Saba has been brought up in isolated Silverlake.

She never sees the dangers of the destructive society outside.

When her twin brother is snatched by mysterious black-robed riders, she sets out on an epic quest to rescue him.

The story's searing pace, its spare style, the excitement of its fabulously damaged world, its unforgettably vivid characters, its violent action and glorious love story make this a truly sensational YA debut novel.
