Into the Land of the Unicorns is the first book in the Unicorn Chronicles by Bruce Coville. A girl, named Cara Diana Hunter, enters the world of Luster with an amulet given to her by her grandmother. On the way, she discovers the world is filled with mystical unicorns and many mythical creatures.
"With a deep breath, and only half believing she will be safe, Cara jumps off the church roof and into the adventure of her lifetime—into the Land of Luster, the world of the unicorns."
In Luster, Cara meets the Dimblethum, the Squijum, and the most magnificent of all the inhabitants, Lightfoot, a rebellious young unicorn. Together the new friends set out on a quest—to reach the Unicorn Queen and prevent the destruction of all unicorns.
