From USA Today & Wall Street Journal bestselling author Michelle Heard comes a new standalone, full-length romance suspense novel.

I was her partner.
Her ride or die.
She was my lifeline.
My sanity.
Until I did the unspeakable.

The unforgivable.

I thought I was strong enough, but I was wrong.
I became the monster I was sent to take down.

Losing my lifeline… there’s no surviving without her.
