For free audio stories for adults, NPR (National Public Radio) has some excellent podcasts with narrative - driven content. Their shows often cover a wide range of topics from current events to cultural stories. Another great resource is Spotify. There are many independent creators on Spotify who share their own audio stories for free. Also, don't forget about Project Gutenberg. You can download e - books from there and then use a text - to - speech app to turn them into audio stories.
One great Christmas book for adults in fiction is 'A Christmas Carol' by Charles Dickens. It's a classic that has been loved for generations. The story of Ebenezer Scrooge's transformation during the Christmas season is both heartwarming and thought - provoking.
The story 'The Forgotten Garden' is also a good choice. It tells of a hidden garden that has been left to grow wild for years. A woman discovers it and spends time restoring it, finding calm and a sense of purpose in the process. The detailed descriptions of the plants and the transformation of the garden are very relaxing.
