Sarah Lotz's extraordinary, unmissable follow-up to the book that made headlines around the world, THE THREE - perfect for fans of The Shining Girls, The Passage and Lost.

Four days into a five day singles cruise on the Gulf of Mexico, the ageing ship Beautiful Dreamer stops dead in the water. With no electricity and no cellular signals, the passengers and crew have no way to call for help. But everyone is certain that rescue teams will come looking for them soon. All they have to do is wait.

That is, until the toilets stop working and the food begins to run out. When the body of a woman is discovered in her cabin the passengers start to panic. There's a murderer on board the Beautiful Dreamer... and maybe something worse.

"DAY FOUR is smart, incisive an d raises real questions about the world in which we live.... But the real praise is that I had to leave the light on in the bedroom after finishing it." - Scotland on Sunday

"Lotz's expertise [is] at orchestrating the mounting tension as the story builds to a wonderfully ambiguous, though satisfying and unusual, denouement." - Guardian

"You'll turn the pages curiously, hungry for clues, until the ending...kicks you in the stomach. Take it to the beach - but maybe not on a cruise." - Entertainment Weekly

"A satirical scream... sign me up for the next cruise!" - New York Times Review of Books

"Chilling, creepy horror set against an all too believable backdrop of human selfishness when the trappings of civilisation are removed. Highly recommended." - Sci Fi Bulletin
