A shame, well in the hopes that I may be able to enjoy these in the future, I'd ask that you petition the Additional resource guide on paizo to add this compendium to their list. I'm not seeing anything that would constitute a 'game-breaker' in this book, and with the hype them adding the kitsune to the choices, it would simply be good practice for Societies to incorporate at least some aspects from a compendium dedicated to them.
