My story that appears in the REUNIONS anthology, published by the Short Story and Flash Fiction Society (on my birthday, believe it or not!), is actually a sequel to another story, one that is soon-to-be published in the OFF THE EDGE anthology by Futurological Press.
So chronologically, the order of the stories is "Christina and the Agency School" and then "Christina and Theresa and Cassandra." But the order of publication is "Christina and Theresa and Cassandra" and THEN "Christina and the Agency School."
I know... more background info than you ever wanted to read about, right? :)
But anyway, you can buy the REUNIONS anthology at Amazon, or even read it for free, if you are a member of Amazon Prime. If you do read it, do me a favor and leave a comment. Somebody once said that reviews are like tips to independent writers, and it's really kind of true.
And also click on over to the SS&FFS website and check them out, they are doing a lot to help promote modern ultra-short fiction!
