My name is Elka. I live at the North Pole with Santa Claus. Every year, on December 1st, I arrive at your family to keep your child waiting until Christmas.
My secret ? I hide in a different place every morning with the help of my parents! But shhhh!!!

The book tells the adventures of Elka, a little elf with magical powers. Elka has fun hiding in every corner of the house, until the day when an event changes the children's daily lives...
