I do agree with the previous poster. But, there are absolutely some great books out there that you can check out. I don't know many of them. I suggest a search on google.com.
I am currently reading The Med School Survival Guide: How to make The Challenges of Med School Seem Like Small Stuff by Jennifer Danek, MD. It is not as detailed as I would want it to be. But, it touches upon pretty much everything you want to know about a med student's life. Even when it may not answer all your questions, it will certainly provide you with the right questions to ask (to other students for eg). I highly recommend it.
