Punky Aloha by Shar Tuiasoa

From HarperCollins:

Meet Punky Aloha: a girl who uses the power of saying "aloha" to experience exciting and unexpected adventures!

Punky loves to do a lot of things—except meeting new friends. She doesn’t feel brave enough.

So when her grandmother asks her to go out and grab butter for her famous banana bread, Punky hesitates. But with the help of her grandmother’s magical sunglasses, and with a lot of aloha in her heart, Punky sets off on a BIG adventure for the very first time.

Will she be able to get the butter for grandma?

Punky Aloha is a Polynesian girl who carries her culture in her heart and in everything she does. Kids will love to follow this fun character all over the island of O’ahu.
