I normally don't go in for "true drama" stories, but I purchased this because it was a daily deal and sounded intriguing. Since that's not my genre of choice, I'm glad I got it on sale, but if you DO generally like that genre, this is a good listen. It's well written, it moves quickly, and it is easy to sympathize with the protagonist. It's almost like a feeling of claustrophobia, imagining what it would be like to realize you're going crazy but not knowing why. I found it interesting enough that I googled both the author and the disease after finishing the book to learn more.
