The Tenth Power (The Chanters of Tremaris #3)

Kate Constable's magnificent musical trilogy reaches its high note as Calwyn returns to Antaris and discovers the true Singer of All Songs.
At the beginning of THE SINGER OF ALL SONGS, Calwyn fled Antaris with Darrow to defeat the ambitious chanter Samis. In THE TENTH POWER, she comes back to the mountains in hopes of rejuvenating her lost powers of chantment. But Samis's magic left terrible scars on Antaris, so Calwyn finds only conflict rather than the peace she craved. Meanwhile, Darrow suffers from a sickness that has sapped his magic as well as his strength--and Samis has returned to continue his quest for the Singer of All Songs. All of Tremaris seems to be dying. How can Calwyn save the land, and finally save them all?
