"Welcome on board The Beautiful Dreamer, your one-way ticket to Relaxation and Fun! Fun! Fun!" Among the hundreds of pleasure-seekers on board The Beautiful Dreamer's five-day cruise are a hard-partying singles group, a couple repairing their marriage, a famous psychic and her beleaguered assistant, and a pair of elderly sisters determined to go out with a bang. For three sun-filled days, the journey seems to deliver all that the cruise brochure promised - a one-way ticket to relaxation and fun in the sun. Until Day Four. Without warning, the ship stops dead. Electricity and cellular signals are cut off. Smoke pours out of the engine room. The passengers and crew have no way to call for help and are stranded in the Gulf of Mexico. At first, all aboard are certain that rescue teams will come looking for them soon. All they have to do is wait. As supplies run low, the toilets stop working and a virus plagues the ship. But when the body of a woman is discovered in her cabin, irritation escalates to panic. There's a murderer aboard The Beautiful Dreamer... and maybe something worse. The chilling, relentlessly suspenseful follow-up to The Three, Day Four is a heart-racing tale from Sarah Lotz, a writer Lauren Beukes hails as "a ferociously imaginative storyteller."
