They're semi-related, semi-unrelated; I would like to have my hands on the book before the workshop, just for the sake of having two avenues of interaction with the author-as-instructor. (She's considering teaching in the Boston area; I'm considering being taught.)

I want to have the book as a general thing, because I'm studying Feri in general and the resources for doing so without an instructor are very limited. The urgency of the desire is linked to the workshop, though.
