My favourite for books to snuggle in bed on a rainy day.
It takes me on holiday when I'm stuck at home. The descriptions are so vivid and the story compelling and warm. Try it even if you didn't like the movies, it has a totally different vibe.

Perfect way to get lost into another world.
Mither Mages Series by Orson Scott Card
Everything aspect of the world is so well developed that you can get lost in that world and truly imagine yourself there along for the journey!
