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.

Which is why she agrees to go to Sunshine Falls, North Carolina, for the month of August when Libby begs her for a sisters’ trip away.

After a wild bet, gourmet grilled-cheese sandwich, and cuddle with a baby goat, Alexis Montgomery has had her world turned upside down.

Honestly, it’s a pretty sweet gig—until her carefully constructed Elsie-verse comes crashing down.

Justin has a curse, and thanks to a Reddit thread, it's now all over the internet. Every woman he dates goes on to find their soul mate the second they break up. When a woman slides into his DMs with the same problem, they come up with a plan: They'll date each other and break up.

Sasha has had it. She cannot bring herself to respond to another inane, “urgent” email or participate in the corporate employee joyfulness program. She hasn’t seen her friends in months. Sex? Seems like a lot of effort. Even cooking dinner takes far too much planning. Sasha has hit a wall. Armed with good intentions to drink kale smoothies, try yoga, and find peace, she heads to the seaside resort she loved as a child.

Felicity “Fizzy” Chen is lost. Sure, she’s got an incredible career as a beloved romance novelist with a slew of bestsellers under her belt, but when she’s asked to give a commencement address, it hits her: she hasn’t been practicing what she’s preached. Fizzy hasn’t ever really been in love. Lust? Definitely. But that swoon-worthy, can’t-stop-thinking-about-him, all-encompassing feeling? Nope. Nothing.

Chemist Elizabeth Zott is not your average woman. In fact, Elizabeth Zott would be the first to point out that there is no such thing as an average woman. But it’s the early 1960s and her all-male team at Hastings Research Institute takes a very unscientific view of equality. Except for one: Calvin Evans; the lonely, brilliant, Nobel–prize nominated grudge-holder who falls in love with—of all things—her mind. True chemistry results.
