Nursing Ghisia, an orphaned stowaway, with a prophecy surrounding her, back to health, Hod, a blind cave dweller, discovers that they cannot be separated and are both plunged into a desperate world of warring clan chieftains and catastrophic power struggles where they must save each other

"A curse is weakening the Norse kingdom of Saylok: no daughters have been born in years. Washed up on these plagued shores, Ghisla is nursed back to health by a blind cave dweller. Named for a mysterious god, the boy, Hod, is surrounded by prophecy. To Ghisla, he's a cherished new friend. When Ghisla sings, Hod can see. Unable to offer safe shelter, Hod urges Ghisla to become a daughter of the temple, where all the kingdom's girl children have been gathered. But because of a magical rune the two cannot be separated, no matter the time or the distance. As Ghisla enters a desperate world of warring clan chieftains and catastrophic power struggles, Ghisla and Hod must defeat the cursed forces that could destroy a kingdom-- and the fated bond between two souls."--,Adapted from back cover
