Query: Even if you think you know about prisons, read this!

I had already done prison work many years ago but I learned a LOT from reding this book. I had thought the book was small for the money, but it was worth every dime. Very short and easy read but crammed with valuable information about how the prison system works and how potential ministers should expect to behave. Nielsen does not go into depth about any aspect of prison ministry but provides excellent guidance about what to expect and how to avoid making mistakes that could be more harmful than helpful to both the minister and the ministy. I highly recommend this book.
