Have you ever read The Man Who Mistook His Wife for a Hat? I had to read it for a neuropathology class, and it was super interesting. It's not just about prosopagnosia, but other odd neurological deficits as well. As someone with prosopagnosia, you might find some solidarity in the case study that inspired the name of the book.
This reminds me of some of the other real life cases in Oliver Sack's collection below. Well worth a read if you're interested in unusual neurological phenomena.
