A Shift in the Earth by Patricia D. Eddy

Farren should have died. Instead, she lost everything.
As the only female to ever lead, she feels the pressure every day. To be more.
A demented group of witches is after the only family she has left, and she’ll do anything to keep them safe.
She shouldn’t trust anyone. Especially not a mysterious—and sexy—man who shows up at her P.I. office looking for the silver wolf.
Eli’s full of secrets he doesn’t know he keeps, and Farren’s going to figure them out. Because he’s more than just a case. He’s her mate.
If Farren can’t protect him, her life is over. But can a broken woman find her strength before it’s too late? Or will she lose Eli forever?
