Good Story with a lot of promise!
I really enjoyed this story. The author feels a lot for all of her characters, and it is obvious in the prose, which moves quite smoothly. There are a few things I would suggest:
Read the story now
1) Title. I'm an English teacher, and I'll admit I love a big, chewy word like "recrudescence". However, since it's probably not a word many of your readers will be familiar with, they might not know what your story is about, and therefore might not click on it. I would consider changing your title to something more readily accessible. (i.e. "Recovery", or "Renewal").
2) Characterizations. I really love your characters of Omar and Sofia, but I felt that sometimes they got lost in the shuffle, and their romantic arc wasn't completely fulfilled. A lot of your episodes go into histories and details of the universe--which I love! But consider adding a little more direct conflict to your chapters, so they don't feel like sections from a history book.
Overall, I loved this story! The characters are believable, and it's a fresh and new take on the shifter genre. Would definitely recommend!
