I bought almost the entire line of the Limited ed 4th direct from AEG in one go, they threw in a freebie or 2 with the order.. one of them was Whispered Secrets..

What you can find online is basically what I originally posted above, in fact, my post over on the FFG (think) L5R site is what got the text only version released..

There are a few people that have said online that they have a copy.. when they tried to get a brazillan version (?) of L5R up and running on a kickstartish site they offered copies to high tier backers (it didn't happen in the end). est 20 odd (?).. I only say this as there was a photo of the 2013 exclusive game it there looked to be about that 50 odd people there and that was a sourcebook, so yes, there should be less if its only for the GM's.. complete guess though..

I've seen 2 copies come up for sale on ebay since I posted in 2013, the other maybe 2 years or so ago.. so averaging 1 every 2 years.. sorry I don't do the scanning thing.. I see there are semi regular requests on reddit and 7chan so one will surface eventually (usually)
