Hey! First I just wanted to say that I really loved the idea behind "My arrogant Alpha", even though I was a little disappointed. I love that a female would actually become an Alpha instead of a male, points for orginality, and I love that she would find her mate to be an Alpha of another pack so I had already fantasized events in my head. However, I was disappointed of her age, I think you'd attract a bigger audience if you make the characters older and more mature, stories where the Alphas are still in school is a tad bit unrealistic (if werewolves actually were realistic lol ;P). As for the writing, try to describe the setting more, exaggerate and the reader will get a much clearer picture and it helps to not make it seem like a checklist.
Sorry for this long note and for putting my foot in my mouth..
I wish you good luck with all your work :)
