Chosen as one of Time Magazine's 100 Best Young Adult Books of All Time, Gullstruck Island is a vibrant and exciting novel, in a beautifully imagined setting, by Frances Hardinge, the Costa Award winning author The Lie Tree. 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, or risk everything.

Can the fate of two children decide the future of Gullstruck Island?'Everyone should read Frances Hardinge.

Everyone. Right now' - Patrick Ness, author of A Monster Calls.
