The river thief

Like many rivers, the banks of the Lyde hold a hoard of forgotten things: pottery, trinkets, a shard of glass. They also hold a Memory. In the days of this story, the buried Memories were forgotten by most - but not by all. When Adderley discovers Ef - a being who seems part human and part fish - in the river by her home, she is drawn into an adventure that challenges everything she's learnt about the world.
