Fireball by Nikki Belaire

Addie
Broke, homeless, and all alone in the world, except for my boxer Pete, I don’t think life could get any worse. Then, of course, it does.
At the wrong place at the wrong time, a crime lord kidnaps me, under the mistaken belief I have the information he wants. When I wake up in his torture chamber, I’m terrified as I slowly realize the horrible truth. He doesn’t want to end me – he wants to keep me.

I love a challenge. Taming the beautiful and feral Addison Scott will be my most enjoyable one yet. When she runs, I chase. I need to see how tough she really is. Imprisoning her in the dungeon, I threaten to let my butchers have at her. Nothing they say or do breaks her except keeping her from her dog.
All she wants is that mutt. All I want is her.
Now I have a prisoner who I’m going to enjoy torturing in a way neither of us ever expected.

** Fireball was originally published as part of the Hell Hath No Fury anthology. The story has been expanded and extended to a full novel. Standalone M/F romance with kidnapping, violence, age gap, possessive hero, and a touch of humor. No cheating. Guaranteed HEA**
