Inside the cave, they find Hefring, a strange woman not keen on strangers. Ailsa slowly gets to know who Hefring is. She is a selkie, a mermaid, a billow maiden from ancient myth.
However, she is stuck on land and slowly dying. It is up to Ailsa and her new friend Camilla to save her, but there are plenty of obstacles in the way – not least Ailsa’s own fears and her mum’s illness. The Billow Maiden is a beautifully told tale of friendship, family, healing and transformation from a stunning new writer for children.
