Wish book series (Lori Evert)

Long ago, a brave little girl named Anja wanted to be one of Santa's elves. So she leaves a note for her family and helps her elderly neighbor prepare for the holiday, then she straps on her skis, and heads out into the snowy landscape. From a red bird to a polar bear to a reindeer, a menagerie of winter animals help Anja make her way to Santa.

"Anja makes a wish to become small during a game of hide and seek - and her wish comes true! Or does it?"--
