Irreversible

Sienna wanted to live a simple life coming back to her pack. She was going to follow her family's foot steps as a doctor of her pack, become delta, and find her mate (not necessarily in that order). But that was until she finds her mate he's her Alpha but instead of welcoming with open arms he welcomes her with him expecting a child with another she wolf. And Sienna has nothing else to do accept stay in the pack and watch the life meant for her get ripped out of her hands.
