Series Review: Abhorsen Trilogy

Synopsis: In the north of Ancelstierre, a normal country with no magic, is a wall that separates it from the Old Kingdom. In the Old Kingdom, there are two types of magic: Charter and Free. Charter Magic is controlled by symbols, while Free Magic is wild and dangerous, but also lets the wielder control the dead. The Abhorsen's job is to use Charter Magic-infused bells to put the dead back where they belong. The books follow Sabriel as she becomes the Abhorsen and then Lirael, who is part of the future seeing Clayr.
