Oh, and after emailing with the author who queried, I told her that her story did not fit the theme of TEoP and that I specifically stated "no alternate dimension" stories.
Her response? Thank you for getting right back to me! I hadn't thought of it as an alternate dimension story, but I suppose it is. (She enters it through a tree, btw; and honestly, I had never categorized it rather than as fantasy.) Now I've got the synopsis for my SF/fantasy bibliography anyway. Thanks!
*looks at my guidelines again*
I'm beginning to get very grumpy about this slushpile business. Thank goodness I got a great story that was interesting, on theme and on genre.
