The Singer of All Songs (Chanters of Tremaris Trilogy, Book 1) by Kate Constable
This book is the first in an excellent fantasy series. I just happened to pick it up and was very pleasantly surprised by what I found. Unlike many fantasy series, the power in this book comes from singing. It was a different way to write this type of story and I really liked it. It is written for young adult and so may be difficult for younger readers, but it is clean an appropriate. In this story, a young chanter Calwyn finds an injured man, Darrow, within the sacred wall of ice. Like her he has the power of chantment, but he is pursued by a dangerous enemy. This enemy is determined to gain mastery over all forms of chantment and become the singer of all songs. Calwyn will also have to master new skills if she is to defeat him.
