The book is good. Like I said before it's hard to make books like these interesting but you did good. I like how you kept the readers hanging on that last chapter.
Read the story now
My most favorite character is the main character. Which you know A+ for giving us characters to like and dislike in the beginning chapters, well done. I like how she tries not to make stupid decisions. I do feel bad for her. I can tell she's going to be a powerful she-wolf later on.
My least favorite character is unfortunately Dio. I don't like how predatory he is with Ari and he tries to take advantage of her while she's in heat ( that's one of the reasons why I feel bad for her). And with her being so young it doesn't sit right with me. It doesn't make your book bad. Your book is still good. I just don't like him personally.
Overall good job.
