This is between a 3.5 and a 4 for me. At times, it read like a hagiography of Purgatory, with a lot of repetition. However, there are points that illuminated different aspects of theology, related to Purgatory, that made this book well worth it.

I will warn people that are prone to scrupulosity to beware the first part of the book, as it could send them down that path of despair if they're not careful.
