'A stunningly beautiful story, full of wild imagination. This is a hold your breath, read in one sitting sort of story...' - Jasbinder Bilan, author of Naeli and the Secret Song

A lyrical 11+ story of dangerous enchantment and sorcery, from Carnegie-shortlisted Chris Vick; perfect for fans of Frances Hardinge.

Hilly Seaborne, fourteen, is an outsider in her new home on the Cornish coast. A skilled acrobat, she is pulled between strange dreams of flying, the call of the sea, and visions of a deserted lighthouse that appears only to her. Magic thickens around Hilly as she begins to uncover tales of strange sightings and unnerving events, alongside her at times frustrating, logic-loving classmate, Lorcan.

As she discovers the truth about her family's past and her connection to the luminous spirits that roam the coast, deadly elemental forces threaten everything she holds dear. Can Hilly control the irresistible power she feels? Who is Isla, the mysterious girl that lived in the invisible lighthouse long ago? And what are the dark forces stirring deep under the water's surface?
