That means you may only have thirty days to buy copies. If you've been thinking you'd like to and just haven't gotten around to it, you can find them at Amazon, at Barnes & Noble, and at Drollerie Press's own site, and most other reputable places where ebooks are sold.
In actuality, the same health crisis that is slowing down all of the press's key processes may slow the takedown of books they no longer have the rights to. Also Amazon and B&N are slow to respond to small publishers, so even if Drollerie does everything properly from here on out, there may be delays. You might have longer than thirty days. But please don't bet on it. My odds of getting my tiny sliver of payment are much better for sales that happen legally.
The word on the street is that Drollerie Press may be sold. I hope so, because that looks right now to be the only way the press will survive. If it sells to someone reputable who has a credible plan for the press, I may offer the Rugosa series to the new management. Certainly, I'll give the situation a little time to settle before I seek to publish the series elsewhere.
That said, I am researching my options, and one way or another, these stories will be available again someday soon. The series will continue.
As a side note, Drollerie Press also published the e-zine that hosts my one venture into podcasting: How the Grail Came to the Fisher King. I don't know how much longer that zine has before it evaporates into 404 Not Found. The podcast itself is under a Creative Commons license, so it's legally a trivial matter for me to post it in other places. I'm not sure exactly when I'll get around to doing so, though. If you want to download the story, that's probably worth doing soon, too.
