A frozen heart - Elizabeth Rudnick

Love is an open door... be careful who steps inside. Anna is a princess of Arendelle. Locked away from the outside world for years, she is desperate to leave her lonely life behind. Her parents are gone, and her sister, Elsa - the only person who might show her love - is cold and distant. Hans is a prince of the Southern Isles. Thirteenth in line to the throne, Hans is desperate to escape the tyranny of his father and older brothers and find a kingdom of his own to rule. Their worlds collide at Elsa's coronation. At first it seems as if all Anna's dreams have come true. At last she has found someone to love! But as Hans's true motivations are revealed, their fairy-tale romance begins to melt away and Anna discovers that love is more a mysterious - and powerful - force than she ever could have imagined.
