After global warming came the Melting. Then came Ark.

The new dictator of Ark wants to silence speech for ever. But Letta is the wordsmith, tasked with keeping words alive. Out in the woods, she and the rebels secretly teach children language, music and art.

Now there are rumours that babies are going missing. When Letta makes a horrifying discovery, she has to find a way to save the children of Ark - even if it is at the cost of her own life.
