Description

The White Lotus meets The Last Thing He Told Me in this domestic mystery about a luxury sailboat found floating adrift in the ocean and the secrets of the missing family who set sail aboard it weeks before...

“Emy McGuire’s tense and claustrophobic debut is the kind of compulsively readable thriller that makes you lose sleep to finish ‘just one more page.’ I inhaled this book!”
—Emma C. Wells, USA TODAY bestselling author of This Girl's a Killer

At the start of summer, billionaire couple Francis and Lila Cameron set off on their private luxury sailboat to celebrate the high school graduation of their two beloved children.

Three weeks later, the Camerons have not been heard from, the captain hasn’t responded to radio calls, and the sailboat is found floating off the coast of Florida.

Empty.

Where are the Camerons? What happened on their trip? And what secrets does the beautiful boat hold?

Set over the course of their vacation and in the aftermath of the sailboat’s discovery, No One Aboard asks who is more dangerous to a family: a stormy ocean or each other?
