I thoroughly enjoyed reading Pack Challenge by Shelly Laurenston. Sara and her friends (Miki and Angie) totally made the book. I was laughing out loud at their interactions.
They live in a town mainly of shifters, although they are not aware. Also, Sara is a shifter and she is not aware either. She works at a motorcycle shop and gets introduced to Zach and his pack, who happen to all be bikers.
Of course, there is another were-pack fighting with Zach's pack and Sara is right in the middle of it. I recommend this to anyone who enjoys a fun paranormal book.
One of my favorite parts of the book is when Sara asks if there are Bunny Shifters.
