The Big Freeze — Christina Soontornvat

A fun-filled chapter book series that answers the question: What if Frozen's Elsa went to regular school?
The time has come for Princess Lina to choose her special magical weather specialty. Her cousin Jack Frost makes amazing snowflakes. Her Uncle Lee forms ice caves in glaciers. Her Great-Aunt Sunder creates winter storms on polar seas.

Gulp.

Everyone has chosen something so impressive. Lina's not sure what she's going to do-- but she's determined to make her mark in a big way!
