You're my mate... I will never let anything happen to you

My name is Natalie, I am 19 years old. I am an actress and ballet dancer... but I am also a shapeshifter! I shape shift into a wolf whenever I feel endangered.
My clan is famous for peace, we have rarely fought with any other clans unless we absolutely have to.
There is a new clan in town, they call themselves the Hoppers. They seem friendly, however, my mate William believes they are acting like this to gain our trust then stab us in the back.
William has always been one to worry, but now with the Hoppers slowly becoming part of our clan, I am beginning to see that the Hoppers are not at all they seem.
