Sometimes reunions bring out the worst in us. A group of nine college friends reunite annually to celebrate the New Year. But when a blizzard strikes while they’re stuck in an isolated lodge in Scotland, old resentments and toxic patterns emerge. By New Year’s Day, one of them is dead and one of them did it. Which of the friends is a killer? A great choice for anyone who enjoys locked-room mysteries.

This 2020 mystery puts a modern spin on Agatha Christie's classic And Then There Were None, setting a destination wedding on a remote Irish island, accessible only by boat, with guests whose lives are connected in ways they never could have guessed. When a magazine publisher weds a handsome reality tv star, she wants her wedding to be magazine-worthy: the designer gown, the atmospheric location, everything perfect to the last detail. But when the guests arrive, including old colleagues, boarding school friends, unreliable family, and untrustworthy friends—things begin going wrong, as long-buried secrets threaten to burst forth at exactly the wrong time. And then they find the dead body. Told in rotating points of view, this was cleverer than I'd expected. An enjoyable mystery that's excellent on audio. (I would have appreciated a content warning for self-harm; a murder mystery is certain to have triggers but that one took me by surprise.)

From the publisher: "From London to Corsica to Paris -- as a young woman pursues the truth about her late mother, two captivating love stories unfurl in this captivating novel from the author of The Guest List. Kate Darling's enigmatic mother -- a once-famous ballerina -- has passed away, leaving Kate bereft. When her grandmother falls ill and bequeaths to Kate a small portrait of a woman who bears a striking resemblance to Kate's mother, Kate uncovers a mystery that may upend everything she thought she knew. Kate's journey to find the true identity of the woman in the portrait takes her to some of the world's most iconic and indulgent locales, revealing a love story that began in the wild 1920s and was disrupted by war and could now spark new love for Kate. Alternating between Kate's present-day hunt and voices from the past, The Book of Lost and Found casts light on family secrets and love -- both lost and found."

From the publisher: "From the author of The Guest List, an evocative love story set along the Italian Riviera about a group of charismatic stars who all have secrets and pasts they try desperately -- and dangerously -- to hide. Rome, 1953: Hal, an itinerant journalist flailing in the post-war darkness, has come to the Eternal City to lose himself and to seek absolution for the thing that haunts him. One evening he finds himself on the steps of a palazzo, walking into a world of privilege and light. Here, on a rooftop above the city, he meets the mysterious Stella. Hal and Stella are from different worlds, but their connection is magnetic. Together, they escape the crowded party and imagine a different life, even if it's just for a night. Yet Stella vanishes all too quickly, and Hal is certain their paths won't cross again. But a year later they are unexpectedly thrown together, after Hal receives an invitation he cannot resist. An Italian Contessa asks him to assist on a trip of a lifetime -- acting as a reporter on a tremendous yacht, skimming its way along the Italian coast toward Cannes film festival, the most famous artists and movie stars of the day gathered to promote a new film. Of all the luminaries aboard -- an Italian ingénue, an American star, a reclusive director -- only one holds Hal in thrall: Stella."

From the publisher: "It's the opening night of The Manor, the newest and hottest luxury resort, and no expense, small or large, has been spared. The infinity pool sparkles; the 'Manor Mule' cocktail (grapefruit, ginger, vodka, and a dash of CBD oil) is being poured with a heavy hand. Everyone is wearing linen. But under the burning midsummer sun, darkness stirs. Old friends and enemies circulate among the guests. Just outside the Manor's immaculately kept grounds, an ancient forest bristles with secrets. And it's not too long before the local police are called. Turns out the past has crashed the party, with deadly results."
