Aubible has an excellent collection of audio books. A good place to start is the Neil Gaiman curated selection. This includes classics and modern works by many of my favourite authors, including Avram Davidson, M John Harrison and Robert Sheckley.
Some particularly good audiobooks include readings by the author and full cast recordings. Here are five of the best.
This is the complete collection of Doctor Englebert Esterhazy’s adventures in the Triune Monarchy of Scythia- Pannonia-Transbalkania, located in a 19th-century Europe between the Wars.
Ellen Kushner turns out to be a great reader of her own work. All three of the Riverside books are available, with a full cast who ably bring the stories to life.
A fine tale of a young witch growing up.
A very disturbing story of a schizophrenic dealing with disturbances in reality, and possible intrusions of mythic creatures.
Yes, all of the His Dark Materials trilogy are available. Not only is Pullman an excellent reader of his own work, but (as with the Kushner) a full cast enlivens the narrative — the attack on the polar bear stronghold is beautifully evoked.
