Nicholson, William

Fifteen-year-old Bowman uses his newly-discovered powers to join with his twin sister Kestrel in an attempt to liberate their people from the "beautiful but cruel" civilization which has enslaved them.

Twins Bowman and Kestrel go on a journey to seek the promised land.

After Kestrel Hath rebels against the stifling rules of Amaranth society and is forced to flee, she, along with her twin brother and a tagalong classmate, follow an ancient map in quest of the legendary silver voice of the wind singer, in an attempt to heal Amaranth and its people.
