"The Compleat Slave: Creating And Living An Erotic Dominant/submissive Lifestyle" by Jack Rinella and Joseph W. Bean
I'm going to chime in and suggest not reading House of God until you are done with your MS3 year. The book is dated, reflects an older technique of teaching medicine, and is much harsher than the reality is today. Until you actually experience the wards, you have no basis for comparison, and all it will do is depress you and give you a misguided view of what you're getting into.
And "The Spirit Catches You and You Fall Down" is a ******ed book that no one should ever read. Only read it if you're pursuing a career in Naturopathic medicine.
