From Ellen Datlow on Facebook, I find that 'A Tiny Mirror' by Eloise C.C. Shepherd has made it to the most prestigious anthology of them all. So that's great news for the author, and rather spiffing for ST.
The book will be published by Nightshade Press in September.
Well done, Elly! Here is a link to the author's website.
If you want to read the story that so impressed Ellen, ST#39 can be bought in printed or digital form.
