In the red corner is a six-foot-three machine of pure mass, an ex-MMA fighter with a bad attitude and fists of steel.

He is my best friend's brother.

But Sofia is not here anymore, and all that she left me were her instructions: take care of my kids.

Not a simple task, especially when I have to open my doors to Sofia's estranged brother.

I spent my entire life dreaming about having a family of my own, but I didn't think it would be through loss that I would find my gain.

Three brilliant children need me, and I'll have to learn to co-parent with a bull of a man in the China shop of my life.

We are complete opposites; I'm the business first, a workaholic in the big city with a penthouse. Then there's Alvaro Castillo, El Toro, with callouses in his hands and ink all over his skin.

I'll need him on my side if I want the best for these kids, but my trust isn't something I give out easily.

To make things worse, El Toro has a secret that might ring the bell of defeat in all of our lives.

Now I have everything I've ever wanted. But at the cost of my best friend's life.

*This is a spicy slow burn romance. Sixteen years of age gap, an ex-MMA fighter, and little miss overachiever. +18.
