Now that you have a slave, what do you do with him or her? I'll tell you right now that this book will not answer that question for you. And for what the introduction claims the book is, it could be a far better guide to how to write "a master manual." The problem is that I've read no other book like it, and am uncertain of where else to point the hopeful reader who doesn't have a leather or kink community available as a local resource. if one keeps the introduction in mind and questions oneself as to what is really, really important in their day-to-day life as is, one can get an idea of how to assign tasks, train and remind a slave or submissive in how to serve specific interests.
Regarding the seemingly endless section about the dinner parties: if you don't have dinner parties, mentally substitute something that you find too time consuming to do yourself, but that you'd love to have someone else take care of for you. Preparing for and attending an Society of Creative Anachronism event? Tending to your artistic space? Buying produce? Tending to your feet? Really, anything truly nitpicky that you want done a certain way -- that section shows you how to give step-by-step detail in writing that a slave or submissive can refer to as they're doing the task.
Other tasks have detail given their importance TO THE AUTHOR. If there are things that the dominant / owner / daddy/ master (hereby known as the grand poobah, because I'm getting sick of typing all that) wants to do themselves, then they either get to specify that those actions are off limits unless specifically mentioned, or don't list them at all. Cleaning? What can be touched, and what should be left alone? How often? Spring cleaning? Seasonal changes, visits, decorations, etc? Who drives? How is the opening of doors dealt with? Dietary preferences and restrictions? If taken with the required grain of salt mentioned in the introduction, this book could help a lot of new people go from having their submissives post about looking for ideas for their grand poobah to having details instructions and a schedule already prepared after the contract is signed and the (training / temporary) collar is locked on.
I wish that Rubel had taken the time to outline his manual as he was presenting his information, as I've read reviews and even talked to people within my community who took offense at his tone because he wasn't being clear on providing a roadmap rather than specific expectations of behavior for all slaves. Indeed, a section regarding the potentially rude behaviors of guests at the above mentioned dinner parties would have been much more clear had it been explained why detailing such rude behavior was necessary to include in the manual; I can make some intelligent guesses, but it seems as though the manual involves a lot of in-references between the author and his slave that should have either been explained or edited out completely. Sidebars, more asides in italics and so on could have gone a long way to keeping otherwise normally intelligent and perceptive people from reading what they were used to reading -- lists of expected behaviors -- rather than what was being presented -- an outline of how to generate the behaviors the dominant reading the book would want for their particular life.
If this book ever ends up going out of print, I hope that the author redesigns it in a second edition rather than simply allow another printing of the same format. When presented in the right way, this could end up being a very valuable workbook for a number of budding ... well, poobahs.
