About this book: A servant serves Master's needs or is fired; A slave serves Master's wants or is released. However, Master's wants must not trump slave's needs, Even when playing by RACK standards. slave is in service to Master; However, Master is in service to the relationship. Welcome to the complex and elegant World of Master/slave relations. This is a revised and substantially expanded version of my prior book, Master/slave Relations: Handbook of theory and practice. Even if you've read that one, this is substantially different. This is a book both for people starting out in M/s and also for people who have been involved for a few years. The second book in this series, Master/slave Mastery: Refining the Fire - ideas that matter is intended for those who have been involved with the Master/slave world for 5+ years. Together, these books are core readings for anyone interested in living in a structured, authority-imbalanced relationship.
