'Pel Narine is on the edge of war, and Anni Tidechild is on the brink of change. Uncertain about her past and fearful of the future, Anni lives a life of evasion; avoiding both her guardian, Wavelord Filip Able, and the voice that calls to her from the sea.
'When she meets Duck Knifetooth, the new friends are catapulted into unforeseen danger: pirates, the last giant, a mysterious ship and ancient creatures of the deep.
'It was a message to the Tidechild from the Pool of Fire in the Deep. Just five words ... We are waiting for you.' (Publication summary)
