Miki: Miki Box Set (Book and Plush) by Stephen Mackey
On Midwinter Eve, Miki and her friend Penguin find their wishes come true, as they are given a little tree to brighten up their cold, dark home. However, keeping the fairy lights twinkling takes more energy than even the great Polar Bear can muster. Miki's friends worry when she suddenly disappears, but her magical underwater journey provides her with a light that is everlasting. Set in a timeless, frozen place with dark blue skies and stark snowy landscapes in beautiful tones, this book evokes winter so thoroughly that the reader cannot fail to snuggle up somewhere cosy and read it.
