The first book in Tamora Pierce's Immortals series, Wild Magic is set about a decade after the final book in the Song of the Lioness Quartet. This book is followed by Wolf-Speaker, Emperor Mage, and In The Hand Of The Gods.
Although it's a children's/teen book, as with her other books, I find that it can be enjoyed by all ages. I certainly do.
In part, this book sets up the world, and it's not particularly needed to have read the other books Pierce has written, as the characters are all introduced here. Also, even though this is the first book in the series, it stands on its own quite well, coming to a satisfying conclusion.
Pierce is great at coming up with unusual and interesting twists on magic for her books and characters. Daine is no exception, the main character for this series and she learns and grows in interesting ways.
Well worth the read, and a book which has stuck in my head over the years. I'm glad to have found it again.
