Looks like potentially interesting book, but it is not exactly that interesting as it focuses on eating slaves only without any of interesting details in various regions, as much as I can see from the sample which is available here

Those last chapters 14-15 may be be most interesting to read so maybe OP coud post some of that if it can be copy pasted from the ebook.
