I used to believe love could survive neglect. I told myself that every skipped screening, every canceled birthday, every moment Declan chose Mia and her "delicate voice" over me and our son was just ambition talking. But when he ripped the only pediatric ventilator off our suffocating five-year-old's stretcher ? so he could rush it to a woman who'd merely inhaled some cigar smoke ? something inside me finally died.

My son, Toby, has severe asthma. While he fights for every breath on a rain-soaked pier, my husband spends his time playing devoted savior to Mia Croft ? the "business partner" he swears is worth ten billion dollars and every ounce of his loyalty. He steps over Toby's stretcher. He calls me hysterical for begging him to save his own child.

So I make a choice. I stop waiting for the ambulance.

I open my own son's airway with a steel needle in the middle of a storm, because no one else was coming. I let the Coast Guard fly us out. And just when I think Declan has already cost us everything, I uncover something far worse.

Toby's inhaler was poisoned ? deliberately, methodically, days in advance. Mia Croft isn't a grieving business prodigy. She's an international fugitive with a body count and a fake name, and my husband handed her our son's life like a business card.

Now the man who chose a cartel assassin over his own flesh and blood is about to learn exactly what it costs to lose the only people who ever truly loved him.

And this time, I won't be the one drowning.
