You can see that Horselover Fat is based on PKD himself within the first few lines which gave me a lot of hope for this book as he did some of his best writing when he was out of his head. I can pretty much say I was let down. I don't mind a difficult read but this was painful at times and there were parts of PKD's psyche I really didn't want to see. I'm also not always enamoured of author's spiritual journeys disguised as something else even if the journey is into madness. Despite this he can still write and write well. He draws his characters well with his prose and at times is still able to build the tension he could easily master in his older works. It just didn't help save this in my opinion.I'll read the other three in the trilogy eventually as I've wanted to read all his works good or bad but I think that will be in a distant future.
