Tamora Pierce

In order to explain Melting Stones, the book I just read, I have to explain the Tamora Pierce books. There's two different universes, the Tortall universe, and the Magic Circle universe. The magic circle universe is about 4 kids that have ambient magic. Tris is a weather mage, Briar is a plant mage, Daja is a metal mage and Sandry is a weaving mage. they can't control their magic, so they're sent to the Winding Circle Temple where they live with Lark and Rosethorn. After they become fully trained mages (as teenagers) they each go on seperate journeys with their main teacher, except for Sandry who gets stuck at home. Briar goes with Rosethorn to Yanjing where they discover Evvy, who is a stone mage. They take her with them and start training her to be a mage.
