There, they find a world in turmoil. The four guilds of magic no longer trust each other. The beloved unicorns have disappeared, and terrible wraiths roam freely.

Scared, the girls return home. But when Sophie vanishes in the night, it will take all of Claire's courage to climb back up the ladder, find her sister, and uncover the unicorns' greatest secret. Blending the timeless wonder of The Chronicles of Narnia with Frozen's powerful themes of identity and sisterhood, The Unicorn Quest will draw you up the chimney into a magical world you'll never want to leave.
