If you prefer your worldbuilding essays in tangible form, you can now get New Worlds, Year Five in print from Barnes and Noble, Books-a-Million, Bookshop.org, IndieBound, and Amazon in the US or in the UK — note that the US link gives me a small commission, but I mention that for disclosure, not as a push for you to buy from Amazon.
Also also! At JordanCon last month they published their (I think) annual) anthology, this time titled Neither Beginnings Nor Endings. It contains my long story “And Ask No Leave of Thee,” which the familiar among you will have recognized as a line from the ballad “Tam Lin;” yes, after several decades, my brain finally produced a Tam Lin retelling! You can get the anthology only from Amazon, in ebook or in print (both of those commission links again).
