Poppy and Alex. Alex and Poppy. They have nothing in common. She’s a wild child; he wears khakis. She has insatiable wanderlust; he prefers to stay home with a book. And somehow, ever since a fateful car share home from college many years ago, they are the very best of friends. For most of the year they live far apart—she’s in New York City, and he’s in their small hometown—but every summer, for a decade, they have taken one glorious week of vacation together.

Nora Stephens' life is books—she’s read them all—and she is not that type of heroine. Not the plucky one, not the laidback dream girl, and especially not the sweetheart. In fact, the only people Nora is a heroine for are her clients, for whom she lands enormous deals as a cutthroat literary agent, and her beloved little sister Libby.

Augustus Everett is an acclaimed author of literary fiction. January Andrews writes best-selling romance. When she pens a happily ever after, he kills off his entire cast. They’re polar opposites. In fact, the only thing they have in common is that for the next three months, they're living in neighboring beach houses, broke, and bogged down with writer's block.

Daphne adorait la façon dont son fiancé, Peter, racontait leur histoire : leur coup de foudre, leur retour dans sa ville natale au bord du lac. Jusqu'à ce qu'il ajoute un chapitre final inattendu : il était, en fait, amoureux de sa meilleure amie d'enfance, Petra. C'est ainsi que Daphne se retrouve en coloc avec Miles, l'ex de Petra, qui vient lui aussi de se faire larguer. Ils n'ont rien en commun, sauf un coeur brisé, une bonne dose de rancoeur et une idée folle : s'afficher en « couple » pour semer le trouble.

Car Harriet et Wyn ont rompu six mois plus tôt, et personne n'est encore au courant. Ce sont leurs dernières vacances dans le cottage où ils retrouvent la même bande de copains depuis dix ans, et ils ne veulent pas gâcher ce moment précieux... alors ils vont jouer la comédie une semaine de plus.

Like an avenging, purple-haired Jedi bringing balance to the mansplained universe, Bee Königswasser lives by a simple code: What would Marie Curie do? If NASA offered her the lead on a neuroengineering project—a literal dream come true after years scraping by on the crumbs of academia—Marie would accept without hesitation. Duh. But the mother of modern physics never had to co-lead with Levi Ward.

Alice Scott is an eternal optimist still dreaming of her big writing break. Hayden Anderson is a Pulitzer-prize winning human thundercloud. And they’re both on balmy Little Crescent Island for the same reason: To write the biography of a woman no one has seen in years—or at least to meet with the octogenarian who claims to be the Margaret Ives. Tragic heiress, former tabloid princess, and daughter of one of the most storied (and scandalous) families of the 20th Century.

The many lives of theoretical physicist Elsie Hannaway have finally caught up with her. By day, she’s an adjunct professor, toiling away at grading labs and teaching thermodynamics in the hopes of landing tenure. By other day, Elsie makes up for her non-existent paycheck by offering her services as a fake girlfriend, tapping into her expertly honed people-pleasing skills to embody whichever version of herself the client needs. Honestly, it’s a pretty sweet gig—until her carefully constructed Elsie-verse comes crashing down.

Harriet and Wyn have been the perfect couple since they met in college—they go together like salt and pepper, honey and tea, lobster and rolls. Except, now—for reasons they’re still not discussing—they don’t. They broke up five months ago. And still haven’t told their best friends.
