Mad Hatter's Bookshelf & Book Review routinely receives books from Publishers and Authors for review consideration. When in doubt assume the book comes from a Publisher or if you follow my New Procurement posts I usually describe the source of said book. I still buy a lot of books as well.
Titan Books, who have pushed 3 official companions to Firefly, have announced they will be publishing a collection of short stories in the Firefly universe along with its characters. So far little is know other than one of the contributor, but we can all hope some good names sign on. That said the one announce writer is none other than Firefly alum Jane Espenson who wrote episode 4 "Shindig" who just happens to be Executive Producer of Caprica. Here is a little from SciFiWire.com quoting Espenson on the anthology:
"I'm writing a short story set in the Firefly universe that someone's putting together. Titan Books is putting together a collection written by various of the Firefly writers. But [it's a] very short story, ... 2,000 words. Oh, I just came up with a very clever little short story that involves Kaylee and Wash, two characters that we haven't seen together that much."
It looks as though more Firefly writers will be involved. I hope Joss dusts of his pen to partake. It seems likely that Whedon collaborator Brett Matthews who wrote the Serenity graphic novels Those Left Behind and Better Days might jump in.
The tip of the hat goes to Aidan for first noticing this grand piece of news.
