Song of the Wanderer
by Bruce Coville
Cara has brought her grandmother's message - "The Wanderer is weary" - to the Queen of the Unicorns. Now she has a new task: she must fetch her grandmother to bring her back to Luster, the world of the unicorns. The journey will be dangerous, but Cara has a unicorn guard . . . and she will make new friends along the way, including the Geomancer, and a persnickety gryphon named Medafil.
