Will Kate and Danny find their mother? A modern, magical twist on the rich hoard of Irish legend.
Kate and Dan are twins. When they were three, their mother Ana walked into the sea. Cormac, their dad, and Mrs Janey who looked after them while he was away, both tried their best to comfort them, but they still missed her. The story begins when they meet the strange Ms Cliona, who lures them to the Underworld on dolphins, surrounded by a cocoon of white light.
Bewildered, they are forced to go through challenge after challenge on wondrous and enchanting islands, where they meet powerful ancient beings known as Síoga. Most of the Síoga are kind. Some are nasty. One, however, is like a mother to them, and they begin to wonder if Ana has really died, or if she is a powerful Síoga who is 5,000 years old.
