Diary of an Ice Princess: Chapter Book Series by Christina Soontornvat

Princess Lina has a life any kid would envy. She lives in a massive palace in the clouds. Everyone in her family has the power to control the wind and weather. On a good day, she can even fly! She loves making lemons into lemon ice, riding wind gusts around the sky, and turning her bedroom into a real life snow globe.There's just one thing Lina wants: to go to regular, non-magical school with her best friend Claudia. She promises to keep the icy family secret under wraps. What could go wrong? (EVERYTHING!)

It's Winter Break at Hilltop Academy and Lina couldn't be more excited. With time off from school, Lina's parents say it's all right for her best friend, Claudia, to come up to their cloud palace for a sleepover (as long as she double pinkie-swears never to tell the royal family secret!). Claudia can't wait to see what it's like to actually be a real princess! But she soon learns that all the stuffy palace protocol isn't nearly as fun as it sounds. The girls just have to get out and play! Claudia suggests they go down to the ground and have some fun with Lina's winter magic.

Princess Lina is loving groundling school. Her magic is still under wraps, she hangs out with BFF Claudia every day, and soon their class is taking a field trip to see penguins at the city aquarium! Up in the sky, Lina's Granddad has decided to invite her mischievous cousin Jack Frost to give Lina extra tutorials in Winterheart magic. But when Jack tags along with Lina to school, his tricks wreak havoc on the big field trip. Can Lina keep her cool and save the day?

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. 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!

Princess Lina's BFF Claudia is desperate for a dog. So Lina decides to use her Winterheart magic to turn a puppy snow sculpture into the perfect pet. But the magical snow dog has a mind of its own — and it's running loose at school! Can Lina get things under control before it's too late?

Exciting things are happening in the skies for Lina's royal family. Her cousin, Iris, is getting married and there is going to be a BIG wedding. Lina gets to be a flower girl in the wedding and Claudia gets to come as Lina's special guest! The girls are giddy as they fly up to Granddad's castle for a weekend of pomp and circumstance. Every Windtamer, Spark-Archer, Sky-Painter, and Winterheart is in attendance in all their finery. But the excitement soon turns stressful when Lina learns one of the wedding traditions: Each guest must present a magical present to the newlyweds.
