As head of Obernewtyn's Farseeker guild, Elspeth Gordie must travel to the lowlands to seal an alliance between Obernewtyn and the rebel forces that oppose the totalitarian Council. Yet her dreams call to her with an altogether different purpose: Elspeth must destroy what remains of the weapons that brought unimaginable chaos, death, and mutation to her world. Leaving the relative safety of the mountains, Elspeth embarks on a journey that takes her across the sea and into the heart of the mysterious desert region of Sador.
