Set sail with ten chilling true stories of cruises that ended in murder, disaster, and disappearance, from the wreck of the Costa Concordia to the vanishing of Amy Lynn Bradley. The answers are often lost at sea.

Endless buffets. Poolside cocktails. Thousands of strangers. And no police on board.

Every year, millions of vacationers walk up the gangway believing they're in safe hands. Most of them are. But when something goes wrong at sea, paradise turns to terror fast. The ship becomes a floating crime scene where evidence gets mopped up, witnesses scatter to a dozen countries, and the people investigating work for the company with the most to lose.

Spanning four decades and oceans around the globe, these ten true stories reveal what happens when the vacation of a lifetime goes horribly wrong:

• A honeymooner vanishes, leaving only a bloodstain on a lifeboat awning.

• The captain of the Costa Concordia flees his capsizing ship while hundreds are still trapped aboard.

• Disney crew member Rebecca Coriam hangs up a phone and disappears forever.

• A fire turns the Carnival Triumph into a sweltering, sewage-soaked nightmare adrift in the Gulf.

• Amy Lynn Bradley, 23, steps onto her family’s cabin balcony in the Caribbean and is never seen again.

Bestselling author Michelle Kaminsky draws on court records, FBI files, and the families who refused to stop asking questions to reveal the dark waters beneath the cruise industry’s glossy brochure.
