I think everyone on the planet has seen the Disney animated film Frozen by now. However, many may not know that it's an adaptation of Hans Christen Andersen's The Snow Queen (original/abridged). It's a fairy tale which centers around a young girl named Gerda who goes on a quest save her young male neighbor and friend Kai from the influences of an evil troll's mirror and the clutches of the Snow Queen.
The film adaptation centers around a young woman named Anna who goes on a quest to find and repair her relationship with her estranged sister Elsa who has trapped their kingdom in an eternal winter. It's a musical, as everyone who has heard "Let It Go" knows, which features several fun supporting characters including a talking snowman named Olaf.
If by some chance you haven't seen the movie, you can borrow it from the library and also check out the original tale, the abridged picture book, and/or one of junior easy reader novels inspired by the film.
