The dramatic conclusion to the bestselling MMA series arrives with Fight for Her #4.

Maddie has left me again, and I can't blame her.

I failed to protect her.

I don't even know if I deserve her and Lily.

But I'm determined to make things right.

First, I'm going to find her father. He's been living on the streets too long. That has to end.

Second, I'm going to give up this career. If she wants me to sit behind some security desk, I'm going to do it. For us.

But when Maddie's father turns up in the hospital, and she flies into town to see him, I learn something that changes everything.

Someone I used to call a friend has threatened my little girl.

The game has changed, and now the only person who's determined enough to win is the one who almost bowed out.

Me.
