These four multifaceted mysteries are perfect summer book club picks.

In Lucy Foley's The Guest List, TV celebrity Will Slater marries editor Julia Keegan in a sparkling ceremony on an island off the Irish coast, but a series of ominous incidents undermine their nuptials. Julia receives an alarming anonymous note about Will, and a dead body is discovered not long after the wedding. Reading groups will enjoy unraveling Foley's stylish, atmospheric mystery and delving into the questions she raises about identity, integrity and truth.

Djinn Patrol on the Purple Line, Deepa Anappara's mesmerizing literary mystery, is narrated by 9-year-old Jai, a clever, funny boy who lives in a slum in India and is obsessed with detective shows. After a classmate goes missing, Jai, inspired by what he sees on TV, undertakes an investigation with the help of friends. As more youngsters disappear, Jai is drawn into a world of danger. Both a suspense-filled adventure and a meditation on Indian society, this is a rewarding selection for any book club.

Liane Moriarty's Nine Perfect Strangers takes place at Tranquillum House, a mind and body-focused health resort where nine guests‚ including struggling romance novelist Frances Welty, hope to cure what ails them. But Masha, Tranquillum's magnetic director, seems to be hiding something, and the atmosphere at the retreat soon turns sinister. Moriarty turns up the tension in this dark yet often humorous tale, which features a wonderfully wide-ranging cast of characters. Themes like self-improvement, power and the nature of community make this thriller a great book club pick. Pick it up in time to watch the TV adaptation, which streams on Hulu later this month, as a group! 

Set in 1940s New York City, Stephen Spotswood's Fortune Favors the Dead introduces readers to private eye Lillian Pentecost and her assistant, former circus knife-thrower Willowjean "Will" Parker. The pair is trying to solve the murder of wealthy Abigail Collins, who was bludgeoned to death with a crystal ball during a wild Halloween party. The case becomes more complex and possibly more dangerous thanks to Will's attraction to Abigail's daughter, Becca. Spotswood's fresh spin on the hard-boiled whodunit will give your group plenty of topics to discuss, including gender, female friendship and the author's use of historical detail. 

Foley (The Hunting Party) outdoes herself again with this page-turning thriller; it's like experiencing Agatha Christie's Murder on the Orient Express and And Then There Were None rolled into one. A wedding taking place between an ambitious magazine publisher and a reality television star on an isolated island off the coast of Ireland, with friends and family in attendance. They all have secrets, and it only takes a few days of drinking games, isolation, and resentments to bring every murky feeling to the surface. The island and the ancient folly where the wedding party stays are themselves characters, adding to the feeling of almost supernatural mystery and the unease that something is lurking in the shadows and getting ready to strike. VERDICT Only a handful of thriller writers can accomplish what Foley does here: weave a complex plot from the perspectives of eight characters plus an omniscient narrator without causing confusion or reader exhaustion when the plot bounces from one person to the next. Fans of Christie, Louise Penny, and Ruth Rendell will absolutely love this book, which doesn't reveal its secrets until the very last page.

Set on a remote island off the Irish coast where a massacre once occurred, this entertaining if uneven mystery from Foley (The Hunting Party) opens just after the high-profile wedding of Will Slater, the star of the reality TV show Survive the Night, and Julia Keegan, an online magazine editor. During the reception, the lights go out, prompting a "scream of terror," which turns out to have come from a server, who reports having seen a lot of blood. Flashbacks from various perspectives, including the bride and her sister, the maid of honor, recount what preceded the server's grim discovery—a body. Meanwhile, Julia is on edge after having received an anonymous note warning her not to marry Will, because he's not who he seems. Foley defers disclosing the murder victim's identity until quite late, but she undercuts the suspense with obvious indications of who it is. The tension of the setup isn't quite matched by the reveals, though the nicely creepy setting compensates somewhat. Readers seeking thrills will find plenty. Agent: Alexandra Machinist, ICM Partners.
