I recently read and thoroughly enjoyed Loftis' book 'Elfin' so I decided to read some of her other books. I was a bit disappointed.
'Elfin' seems to have the same storyline as this series, except with elves instead of wolves, and both are just 'Twilight' with different mythical species.
Also, as mentioned in some other reviews, there are a lot of mistakes, as if the book was not proofread. This sometimes makes it difficult to understand. As well as this, 'canis lupus' which is supposed to mean 'grey wolf', or is at least used to identify the grey wolves, actually means 'dog wolf' in Latin...
Lastly, it is annoying that the point of view constantly changes and, not only that, a part of the story is told from one character's point of view, and then the entire thing was told again from another character's point of view.
I don't want to seem harsh, it really just depends how much you're willing to put up with, but if you like the storyline, I recommend 'Elfin'. However, this book is free so you're not losing anything if you want to try it.
