Meanwhile, Darrow has broken away from the group to form a new alliance of his own. Can he still be trusted? In this audiobook, Calwyn's quest for peace and justice has greater consequences than she ever could have imagined.

Calwyn has lived all her life among the priestesses of Antaris, tending to her bees and dreaming of the mysterious world beyond the Wall. Then she discovers a man lying unconscious within the Wall, Darrow, who tells her of the fear and hatred that hold sway in the Outlands, where the magic arts of chantment are disappearing. They journey together to cities of golden stone and seas ruled by blood moons, gathering other chanters to them. For it will take an unprecedented unity to stand in the way of Samis, a ruthlessly ambitious sorcerer who seeks to become Emperor of all Tremaris. Reminiscent of such classic novels as A Wizard of Earthsea and The Hero and the Crown, yet set in an utterly original world where enchantment is worked by singing, The Singer of All Songs stands out from the choir of new fantasies for the warmth of its vision and the beauty of its voice.

Calwyn used to be exceptional. She was the most talented of all the chanters of Tremaris, and she'd fought hard to become their leader. But then there was an accident, and the magic inside her went silent. Where there once was power, now there is nothing. Her whole life, the future she had planned with Darrow, has somehow slipped away. All Calwyn wants to do is limp home and hide. But she can't, because although her power is gone and taken all happiness with it, her responsibilities seem to grow every day. There's a sickness attacking the chanters of Tremaris, a sickness that seems to have infected the land itself. And even though Calwyn is now just an ordinary girl with no magic left in her, she can't sit by and watch the world die. This is a story about tremendous courage and the strength of spirit that life sometimes demands. But it's also a story of hope, because sometimes when everything you know has failed you, there is another way. Sometimes there is a tenth power, if only you can find it.
