We've already finished the first season, which is all Netflix has at the moment, but it was amazing.

We found that this show was about werewolves, defending their lifestyle while hiding from the humans, who were all over their properties in order to solve a local murder, which was in turn caused by other werewolves who were not a part of the pack. I'm not saying any more about it, but this is definitely a GREAT show.
If you like True Blood, the show, you would love this series. I'm sure of it!
Also, it is based off of a series of books. When I found this out, me being the reader that I am, decided to get the ebook from my local library, and have since read the majority of the first book, and while the book is COMPLETELY different than the series, I love it. It's just as good as watching the show, despite the only similarity being location and characters.
Again this is a great series, and an even better book!! :-D
