If you like Fantasy here are a few great stories paired with excellent narrators:
Storm Front (Jim Butcher) - Narrated by James Marsters
The Name of the Wind (Patrick Rothfuss) - Narrated by Nick Podehl
The Way of Kings (Brandon Sanderson) - Narrated by Kate Reading and Michael Kramer
A more complete
fantasy audiobook list is here, but these are my favorite three.
