'If you like dark you will love Mark Lawrence. And when the light breaks through and it all makes sense, the contrast is gorgeous' – Robin Hobb

Only when it's darkest can you see the stars.

East of the Black Rock, out on the ice, lies a hole down which broken children are thrown

On the vastness of the ice there is no room for individuals. No one survives alone.

To resist the cold, to endure the months of night when even the air itself begins to freeze, requires a special breed. Variation is dangerous, difference is fatal. And Yaz is different.

Torn from her family, from the boy she thought she would spend her life with, Yaz has to carve a new path for herself in a world whose existence she never suspected. A world full of danger.

Beneath the ice, Yaz will learn that Abeth is older and stranger than she had ever imagined.

She will learn that her weaknesses are another kind of strength. And she will learn to challenge the cruel arithmetic of survival that has always governed her people.
