Synopsis

When Caroline Lash arrives in Greenhead, Massachusetts, she falls head-over-heels for Van Whittaker, a fleece-wearing, litter-collecting, kayak enthusiast with long, floppy hair and the personality of a border collie. Born and raised in this picturesque coastal village, Van runs with the same crowd he did as a kid: His ex-girlfriend, Bailey, a beautiful girl who attracts men like moths to a flame; Augusta, old money, horsey, and snobbish; and Fran, surrounded by brothers and sons, too fed up with boys to ever consider marrying one.

Together, the group runs wild through the marshes, beaches, and bars of Greenhead, drinking on houseboats, spending long afternoons sunbathing with their children, and playing games the way they always have. But when Bailey discovers that she is pregnant with Van’s baby, the delicate balance of the group’s friendship is thrown off. Soon Caroline is cast out of the circle and what she does next—in a potent mix of fury and heartbreak—exposes long-held secrets and works the entire town of Greenhead into a lather.

Caroline

Boston Cream

It could have been a Boston cream, puffy white, the inside sweet vanilla pudding, but instead it was a jelly donut, glazed with sugar, filled with the sort of fluorescent red goo that could only be created in a ­food-science lab. Caroline didn’t even realize she’d stepped on the thing. She was dragging a suitcase, a backpack was thumping on her back, and her eyes were on the track numbers blinking in green over the platform doors. The voice over the loudspeaker was blaring boarding instructions, and Caroline dashed to her train, legs scissoring, suitcase wheels spinning along. Her shoe must have hit the jelly donut from the perfect angle, because when it burst, the jelly squirted straight up, directly hitting the crotch of her light jeans. She ran along the platform, feet pounding, oblivious, and by the time she hoisted her bag onto the overhead rack she had managed to coat her entire inseam with the sticky fuchsia slime, something she only noticed as she flopped down into her leather seat.

“Oh my God, what on earth?” Caroline muttered, her glasses fogging in the warmth of the train. She unzipped her backpack and rummaged for a tissue. She had a computer, a charger, two lip balms, a book, a pouch full of pens, and a can of almonds. No tissues. “Does anyone have a Kleenex or a napkin?” she called out to the surrounding seats. The woman sitting across the aisle glanced up, made a horrified face, and shook her head before burying her nose back in her phone. Lovely. Caroline pulled a receipt from her wallet and started trying to wipe at the mess.

“Here.” A hand appeared with a sheaf of paper napkins.

“Thank you so much.” Caroline sighed, grabbing the napkins and wiping the jelly from her crotch. “This is such a disaster. I might need to change. Do you know which train car has the bathroom?”

“Oh, no, I’m sorry, there aren’t bathrooms on the commuter rail. None at the station either.”

Why we chose it...


This novel captures the precise, complicated dynamics of a lifelong friend group, from the ways you can communicate full sentences with a single glance, to the longstanding loyalties—and tensions—bubbling just under the surface.


This was a refreshing depiction of a 30-something cast determined to hold onto their youth, even when late nights lose their luster and mornings are spent nursing newborns instead of hangovers.


We couldn’t stop gossiping about this book’s drama at our desks…so much so that other team members kept asking us what was going on in the Editorial Corner (and how a case of head lice could make us cry).
