Mine

Thea’s mom would tell her stories about finding her mate. How it was a magical experience that everyone wants to have. How it was about finding your perfect other half.
She also heard that long ago you could even have two mates; if one died then you would have the other. The catch was: you could never have them both at once. You never knew that the other one existed. It’s whoever you find first. But it was also just a story; a myth.
So when Thea finds her mate, the alpha of another pack, she is surprised. Because she already has one.
What will Thea do? You’re not supposed to have two mates at once! What has the fates done, and how will Thea be able to choose?
