Macy Sorensen is settling into an ambitious if emotionally tepid routine: work hard as a new pediatrics resident, plan her wedding to an older, financially secure man, keep her head down and heart tucked away. But when she runs into Elliot Petropoulos - the first and only love of her life - the careful bubble she’s constructed begins to dissolve.

Eighteen years of summers spent in a beach house in Ogunquit, Maine, have brought Violet Mitchell and Will Seaberg together. For two perfect, beach-filled months every year, they spent every waking minute together. First as friends, until one summer changed everything. But before the two even had a chance to claim the love they’d spent their entire lives creating, disaster struck, tearing the two lovers—and their families—apart.

Successful, handsome and a little bit OCD finance guru Oliver Blake believes he has the perfect life. Until his fiancée leaves him on their wedding day, and his carefully constructed world crumbles around him. Still trying to piece his life together six months later, the last thing Oliver needs at his brother’s wedding is a bubbly British bridesmaid plunging his life into more chaos.

Naomi wasn’t just running away from her wedding. She was riding to the rescue of her twin. Too bad for Naomi, her evil twin hasn’t changed at all. After helping herself to Naomi’s car and cash, Tina leaves her with a niece she didn’t know she had. Now, she’s stuck in town with no car, no job, no home - and an 11-year-old to take care of. Since Naomi’s life imploded right in front of him, the least Knox can do is help her out. And just as soon as she's out of trouble, he can get back to his peaceful, solitary life. That’s the plan, until the trouble turns to real danger.

I got her fired. Okay, so I’d had a bad day and took it out on a bystander in a pizza shop. But there’s nothing innocent about Ally Morales. She proves that her first day of her new job in my office, after being hired by my mother. So, maybe, her colorful, annoying, inexplicably alluring personality brightens up the magazine’s offices that have felt like a prison for the past year. Maybe, I like that she argues with me in front of the editorial staff. And maybe, my after-hours fantasies are haunted by those brown eyes and that sharp tongue.

Belly measures her life in summers. Everything good, everything magical happens between the months of June and August. Winters are simply a time to count the weeks until the next summer, a place away from the beach house, away from Susannah, and most importantly, away from Jeremiah and Conrad. They are the boys that Belly has known since her very first summer—they have been her brother figures, her crushes, and everything in between. But one summer, one wonderful and terrible summer, the more everything changes, the more it all ends up just the way it should have been all along.

Olive Torres is used to being the unlucky twin: from inexplicable mishaps to a recent layoff, her life seems to be almost comically jinxed. By contrast, her sister Ami is an eternal champion...she even managed to finance her entire wedding by winning a slew of contests. Unfortunately for Olive, the only thing worse than constant bad luck is having to spend the wedding day with the best man (and her nemesis), Ethan Thomas.

Polly Fletcher loves marrying off her friends. Which is kind of weird, considering she has no intention of ever walking down the aisle herself. Social worker by day, sex siren by night, Polly relies on exactly three things to get her through life: her Tinder app, her Jimmy Choo shoes and a packet of condoms in her clutch. So when she meets a sexy, silver-eyed stranger at a friend’s wedding, all she’s after is a wild night between the sheets.

Meredith's family's annual game of assassin at Martha's Vineyard during a summer wedding is the perfect chance to honor her sister's legacy, and finally join the world again. But when she forms an alliance with a cute groomsman, she's at risk of losing both the game . . . and her heart.

After years of working her tail off at her event-planning business, Maggie Mitchell is ready for a vacation. With nothing on her mind but R & R, she’s enjoying the warm weather of Bora Bora when in saunters Brody McFadden, her brother’s best friend and also her sworn enemy. Thanks to years of tension between the two—kicked off by a make-out session at her brother’s wedding that ended horribly—Maggie has sworn to stay away from the man. That is, until she finds out he’s in Bora Bora for his boss’s daughter’s wedding, hoping to use the trip to win a real future at the company.
