'When Will and Annalie's father disappears, they set out on a perilous sea voyage to find him. The motley crew of runaways put their faith in each other, and in a small sailing boat called the Sunfish. In a world transformed by a catastrophic Flood, they embark on an adventure that will test their ingenuity - and their friendship - to the limits...The crew face off against storms and pirates, but the biggest threat of all comes from the Admiralty, the all-powerful navy that rules the oceans of the world. The Admiralty are supposed to be the good guys, but the deeper the Sunfish voyages into the Moon Islands, the more they realise that nothing is what it seems.'

'Once more, Annalie, Will, Essie and Pod set out on the Sunfish to look for Spinner - their only clue a coded list Spinner left behind, naming four scientists who were once his colleagues on a top-secret project...When a terrible storm separates the crew and almost wrecks the boat, Will and Essie must use all their courage and ingenuity to try and make their way back to the others. Meanwhile, Pod and Annalie, travelling in the crippled Sunfish, are captured by pirates, who agree to fix the Sunfish - at a price...Not all of Spinner's former colleagues can be trusted. Worse still, their old nemesis Beckett is still on their trail. Can they follow the clues, track down the scientists, and find Spinner before Beckett does?..The second breathtaking adventure in the Quest of the Sunfish series...' (Publication summary)

'The adventures of the Sunfish conclude as twins, Annalie and Will, discover the truth of what was behind their father's disappearance and face even more dangers on land than they did at sea. What awaits them beyond Sundia's Skeleton Coast—the greatest danger they have yet faced, or answers and journey's end at last? The thrilling finale to the Quest of the Sunfish series.'
