New York Times bestselling author Lynn Kurland returns to her enchanting Nine Kingdoms saga as the epic adventure of a weaver and an elven prince continues.

Aisling of Bruadair is frantic to find both the truth about her future and a mercenary to save her country. When an offer of aid comes from an unexpected direction, she is relieved her quest is almost complete. But she soon realizes her task is far from over . . . and will include perils she never dreamed she would ever face.

Rùnach of Ceangail has offered to help Aisling with her quest, then he fully intends to take up his life as a simple swordsman far from magic and evil mages. Unfortunately, a chance finding of a book of indecipherable spells tells him that an ordinary life is never going to be his--especially when he realizes that the book he has in his hands belongs to a black mage who will stop at nothing to have it back.

With time running out, Rùnach and Aisling must solve what seem to be unrelated mysteries before others find those answers first and plunge the Nine Kingdoms into a darkness it will never recover from . . .
