Once You're Mine by Morgan Bridges

Murder brought us together. Only death can keep us apart.

The Tormentor
Calista belongs to me... she just doesn't know it.
The first time we met, I wanted her. The next time, I was obsessed.
I watched her. I followed her. It only deepened my need to possess her.
Once she's mine, I'm never letting her go. 

The Target
Hayden Bennett is a monster, in and out of the courtroom. Unfortunately, I need his help.
What was supposed to be a simple transaction turns into something else. Something intense.
He's always there when I need him, but I don't know if trusting him is a good idea... 

Once You're Mine contains a morally gray hero who is an over the top jealous/possessive stalker and is willing to do whatever it takes to have the heroine.
