House of God - Samuel Shem: The classic intern year book. It is the source of a ton of quotes/jokes/references that you will see here, on TV, and elsewhere. Think Catch-22 but with medical interns instead of bomber pilots. Some weird sex stuff.
Cutting for Stone - Abraham Verghese: Medical/coming of age novel about a surgeon in post-colonial Ethiopia. It is a good novel, with a good bit of surgical scenes. The author is a surgeon. Think The Power of One but with surgery instead of boxing (and a different country).
The Immortal Life of Henrietta Lacks - Rebecca Skloot: Non-fictional story of the woman behind one of the most important cell lines and how that came to be. I was surprised and humbled when I read this book to find that I had sold those cell lines at a previous job, without ever knowing or wondering where they came from. There is an HBO series now. I haven't watched it, so I don't know how it compares to the book.
