My wife and I recently started enjoying this! It's a very calming way to wind down in the evening instead of another installment of $TV_SHOW. I've been narrating Bram Stoker's Dracula, and I must say, the imagery and scenes stick in my mind much better than when I (quite quickly) read silently.
It's fun doing the voices, and taking time every now and again to discuss what happened gives us a more engaged sort of relaxation that's at our direction. It was a bit of a challenge finding a book we both agreed upon because we have very different taste, but we were able to meet in the middle by starting with a classic.
