Bay's gone blank. She doesn't remember her house built on the red earth of Western Australia, nor that her garden is on the coral reef of Ningaloo. She has forgotten that she fought to save the oceans and that humpback whales were her family. She doesn't recognize the faces that look at her now. Not even Scott's, even though they say she used to be mad about him. Her mother is a mystery and she has only a few photos of her father, along with his many books about oceanography. All the same, she will have to take over his maritime tourism business in Exmouth. Jude works there and even though he is now just a stranger, she feels that they were once united by something more than he is willing to acknowledge. In her attempt to reconstruct a past erased from her mind, she will encounter multiple versions of who she was, revealing hidden truths and secrets.
