The Unicorn Chronicles consists of four young adult fantasy novels by Bruce Coville about the fantasy world of Luster that lies parallel to our own. Within this realm exist all sorts of fantastical and mythological beasts, from the familiar unicorn to the strange, squirrel-like creature known as the Squijum. Cara Hunter is sent to Luster via a magical amulet, given to her by her grandmother, Ivy Morris. She is asked to tell the Queen of the Unicorns that "The Wanderer is weary," and must set out in search of the Queen. Along her travels, she befriends the world's inhabitants, such as Lightfoot, a young unicorn prince, M'Gama, a Geomancer who draws magical power from the earth, and the Dimblethum, a bearlike creature, among many others.
