Synopsis
On Gullstruck Island the volcanoes quarrel, beetles sing danger and occasionally a Lost is born... In the village of the Hollow Beasts live two sisters. Arilou is a Lost – a child with the power to depart her body and mind-fly with the winds – and Hathin is her helper. Together they hide a dangerous secret. Until sinister events threaten to uncover it. With a blue-skinned hunter on their trail and a dreadlocked warrior beside them, they must escape. Can the fate of two children decide the future of Gullstruck Island?
