Nine people gather at a luxurious health resort in the Australian bushland. Will they have sex, fall in love, get killed, or maybe just lose weight?Moriarty (Truly Madly Guilty, 2014, etc.) is known for darkly humorous novels set in the suburbs of Sydney—though her most famous book, Big Little Lies (2014), has been transported to Monterey, California, by Reese Witherspoon's HBO series. Her new novel moves away from the lives of prosperous parents to introduce a more eclectic group of people who've signed up for a 10-day retreat at Tranquillium House, a remote spa run by the messianic Masha, "an extraordinary-looking woman. A supermodel. An Olympic athlete. At least six feet tall, with corpse-like white skin and green eyes so striking and huge they were almost alien-like." This was the moment when the guests should probably have fled, but they all decided to stay (perhaps because their hefty payments were nonrefundable?). The book's title is slightly misleading, since not all the guests are strangers to each other. There are two family groups: Ben and Jessica Chandler, a young couple whose relationship broke down after they won the lottery, and the Marconis, Napolean and Heather and their 20-year-old daughter, Zoe, who are trying to recover after the death of Zoe's twin brother, Zach. Carmel Schneider is a divorced housewife who wants to get her mojo back, Lars Lee is an abnormally handsome divorce lawyer who's addicted to spas, and Tony Hogburn is a former professional footballer who wants to get back into shape. Though all these people have their own chapters, the main character is Frances Welty, a romance writer who needs a pick-me-up after having had her latest novel rejected and having been taken in by an internet scam—she fell in love with a man she met on Facebook and sent money to help his (nonexistent) son, who'd been in a (nonexistent) car accident. How humiliating for a writer to fall for a fictional person, Frances thinks, in her characteristically wry way. When the guests arrive, they're given blood tests (why?) and told they're going to start off with a five-day "noble silence" in which they're not even supposed to make eye contact with each other. As you can imagine, something fishy is going on, and while Moriarty displays her usual humor and Frances in particular is an appealing character, it's all a bit ridiculous.
Fun to read, as always with Moriarty's books, but try not to think about it or it will stop making sense.

Send a motley crew of hurting but comfortably heeled Aussies to a secluded resort for a pricey 10-day -Mind and Body Total Transformation Retreat- and what happens? In this cannily plotted, continually surprising, and frequently funny page-turner from bestseller Moriarty (Big Little Lies), nothing like the restorative reset they-re anticipating. The nine guests at Tranquillum House include middle-aged romance writer Frances Welty, her normal spunkiness shaken by recent personal and professional setbacks, and 20-year-old Zoe Marconi, there with her parents on the anniversary of the family tragedy that shattered their lives. What they haven-t reckoned on is Tanquillum House-s messianic but precariously stable director, whose secret agenda could be dangerous to their health. It would be unsporting to disclose more about Moriarty-s largely endearing cast, since her progressive revelations about them contribute so much toward making this such a deeply satisfying thriller. Moriarty delivers yet another surefire winner. Author tour. Agent: Faye Bender, Faye Bender Literary. (Nov.)
