Knuckles by Marteeka Karland

Hannah’s stubborn, abrasive, and vicious. She’s also mine.
Hannah: My life as I knew it ended the night my boyfriend tried to rape me. I killed the swine, and I’m not sorry. After that night, it became my mission to rid the world of as many predators as I could. If that meant I got slapped around a little, I’d sacrifice for the cause. What I didn’t count on was my brother’s best friend coming to my rescue. That dangerous vibe he’s giving off is making me feel things I never expected. Knuckles fought for me. Protected me. Now he’s using words like “claim” and “old lady,” but I’m not sure I want to be anyone’s property. Not unless it means he’s my property too.
Knuckles: I came to Afternoon Delytes to get the information I needed to destroy a woman who’d betrayed me. I never expected to see my best friend’s sister take a backhand to the face. She has the biggest heart of anyone I’ve ever met. She’s also vicious. And mine.
