Two years ago, Holli's ex-fiancé burned to death. She just saw him on her honeymoon cruise.

This was her perfect new beginning. A luxury ship. A loving new husband. A fresh start. But as the coastline disappears, Holli sees him in the crowd, a man with Caleb's eyes, Caleb's smile. A man who died in a fire she barely escaped.

It must be a hallucination. A symptom of her trauma.

Then the "accidents" start. A near-fatal fall on the pool deck. A sudden, violent illness. Her new husband, Landon, is the target.

Holli knows Caleb is alive. He's here, on this ship, stalking her from the shadows. And he's intent on reclaiming what he believes is his... even if it means getting her new husband out of the way. Permanently.

Landon thinks she's cracking under the strain, trapped in the past. The ship's doctor blames her medication. Miles from land and surrounded by strangers, Holli is completely isolated. Is she losing her mind? Or is she trapped in a deadly game with a monster everyone else believes is dead?

What Happened at Sea is the fourth standalone novel in the pulse-pounding Deadly Itinerary series. A gripping psychological thriller perfect for fans of Freida McFadden, Lucy Foley, and Shari Lapena.
