And now, Elsa will be setting sail for a grand tour of the world--leaving Anna behind. But after a mysterious sickness strikes Arendelle, Elsa's tour is delayed, giving Anna the perfect opportunity to finally help. When Anna discovers a secret room in the castle and incants a magic spell, she hopes it will make her dream of curing the sickness come true. Instead, a more sinister dream comes to life: Anna's childhood nightmare of a giant fearsome wolf. Joined by her sister, Olaf, Kristoff, and Sven, Anna must venture into the unknown to stop the nightmare wolf before it destroys everything she holds dear. Anna's quest to save the kingdom will lead her to myths and wonders beyond compare, and require bravery, honesty, and, above all else, love. This thrilling original middle-grade novel bridges the epic adventures of Frozen and Frozen II."-- Publisher's description.
