Frozen heart by Elizabeth Rudnick

Frozen Heart series. Disney Paper Rocket, 2016. ISBN 9781484730515
(Ages: 9+) Fans of Frozen the Disney movie released in 2013 will recognise a large amount of the similarities to the film's dialogue included in this new novel written by Elizabeth Rudnick. There is a definite fan-fiction element to the writing, as the stories of Anna and Hans are developed instead of Elsa's and Kristoff's. Each chapter alternates as the characters narrate their stories. Young Anna is confused and concerned by the imprisonment of her sister Anna, after the incident when she magically filled the ballroom with snow. We are introduced to Prince Hans' background; he is the thirteenth and youngest son of King of the Southern Isles, bullied by his older brothers. He works his way into being the king's favourite, with the goal of attending the coronation of Princess Elsa and marrying her.
When Anna meets Hans at the coronation, there is an instant attraction and she desperately wants to say yes to his proposal. Of course, when she asks for her sister's permission, Anna becomes angry; she creates an everlasting winter in Arendelle and then flees into the mountains.
Elizabeth Rudnick's action and adventure novel explores the motivations of Elsa and Hans, what drives them to act in certain ways. With the themes of love, sacrifice, greed, selfishness and the fight of good and evil, Frozen Heart is suited to a preteen audience who grew up with the movie.
