I heard back from Abyss and Apex today. They didn't accept "Catkin," so now I have my first rejection letter. I would, of course, have been more excited if they had accepted it, but I am still excited to have received a rejection letter - it's a mark of progress. In addition, it was a very kind rejection letter and they encouraged me to submit again. While it's quite possible that it is a stock letter, nonetheless, as these things go, it was a very nice one to get as my first.
