From New York Times and USA Today bestselling author Nicole Blanchard comes a forbidden enemies-to-lovers military romantic suspense!

He's the last person I ever wanted to see again.

Callum Reece. My late husband's brother.

The man who took my virginity

and then left without so much as an I'm sorry.

The Marine operator who makes a living

from putting his life on the line.

But loving me? That had been too much of a risk.

I'm the one woman he can't have.

After he left, I moved on. I built a life without Callum

...until it came crashing down around me.

All I want is to find out the truth about

my husband's death, no matter what it may be.

Sometimes the forbidden is a dangerous temptation.

But when Callum comes back, determined to win my heart,

I'll have to put up the fight of my life to avoid being hurt again.

Operator takes place in the First to Fight series, but may be read as a standalone.
