Princess Anna, Queen Elsa, Olaf the snowman, and all the stars from Disney Frozen are back in an all-new magical chapter book series. After years apart, Anna and Elsa are finally getting to know each other as sisters. But Anna still wishes she could remember the magical times they had together when they were younger--skating and making snowmen, even in the middle of summer! An eager young troll claims he can restore the memories that Pabbie removed, but Elsa's not so sure. Maybe it's time to make new memories!
