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.

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.

Hannah Brooks looks more like a kindergarten teacher than somebody who could kill you with a wine bottle opener. Or a ballpoint pen. Or a dinner napkin. But the truth is, she’s an Executive Protection Agent (aka "bodyguard"), and she just got hired to protect superstar actor Jack Stapleton from his middle-aged, corgi-breeding stalker.

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.

Hi, my name is Bree Camden, and I’m hopelessly in love with my best friend and star quarterback Nathan Donelson (so is half of America, judging by the tabloids and how much the guy dates). The first step is admitting it, right? Except, I can never admit it to him because he clearly doesn’t see me that way, and the last thing I want is for things to get weird between us. Nothing but good old-fashioned no-touching-the-sexiest-man-alive platonic friendship for us! Everything is exactly how I like it! Yes. Good. (I’m not crying; I’m just peeling an onion.)

Everyone says opposites attract. And they must be right, because there’s no logical reason why I’m so drawn to Colin Fitzgerald. I don’t usually go for tattoo-covered, video-gaming, hockey-playing nerd-jocks who think I’m flighty and superficial. His narrow view of me is the first strike against him. It doesn’t help that he’s buddy-buddy with my brother. And that his best friend has a crush on me. And that I just moved in with them. Oh, did I not mention we’re roommates?

Ama Torres is an optimistic wedding planner who doesn’t believe in marriage. But weddings? They’re amazing. Elliot Bloom is a brooding florist who hates owning a flower shop…until a certain bright-eyed, donut-loving workaholic shows up at his door. Once upon a time, they collaborated on events by day, and by night, Ama traced the intricate flower tattoos etched along his body. Then Ama shattered his heart and never spoke to Elliot again. Now they’re working on an event that could make or break both of their careers—except neither of them has gotten over what happened two years ago.

Malibu: August 1983. It’s the day of Nina Riva’s annual end-of-summer party, and anticipation is at a fever pitch. Everyone wants to be around the famous Rivas: Nina, the talented surfer and supermodel; brothers Jay and Hud, one a championship surfer, the other a renowned photographer; and their adored baby sister, Kit. Together the siblings are a source of fascination in Malibu and the world over—especially as the offspring of the legendary singer Mick Riva. The only person not looking forward to the party of the year is Nina herself.

Welcome to the most tumultuous summer of the 20th century. It's 1969, and for the Levin family, the times they are a-changing. Every year, the children have looked forward to spending the summer at their grandmother's historic home in downtown Nantucket. But like so much else in America, nothing is the same.

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.

On a perfect June day, Vivian Howe, author of 13 beach novels and mother of three nearly grown children, is killed in a hit-and-run car accident while jogging near her home on Nantucket.

Vivi also is granted three “nudges” to change the outcome of events on earth.

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.

Laurie is sure love at first sight doesn't exist anywhere but the movies. But then, through a misted-up bus window one snowy December day, she sees a man who she knows instantly is the one. Their eyes meet, there's a moment of pure magic...and then her bus drives away. Certain they're fated to find each other again, Laurie spends a year scanning every bus stop and cafe in London for him. But she doesn't find him, not when it matters anyway. Instead they "reunite" at a Christmas party, when her best friend, Sarah, giddily introduces her new boyfriend: the man from the bus.

Gwen Castle's Biggest Mistake Ever, Cassidy Somers, is slumming it as a yard boy on her idyllic Nantucket-esque island this summer. He's a rich kid from across the bridge in Stony Bay, and she hails from a family of fishermen and housecleaners who keep the island's summer people happy. Gwen worries a life of cleaning houses will be her fate too, but just when it looks like she'll never escape her past - or the island - Gwen's dad gives her some shocking advice.

Seventeen-year-old Reagan seems like the perfect small-town girl. Dubbed a saint by her older brother, Lincoln, she serves the community, makes straight A’s, attends church, spends her summers working with special needs children, and is a piano-playing prodigy. When you’re the daughter of the mayor and the police chief in a sleepy Kansas town, toeing the line is easier than the alternative. That is, until her brother’s best friend changes the rules.

Just when Avery is ready to give up on the summer altogether, she meets Brooks - mysterious, frustratingly charming Brooks - who just happens to be on staff - which means he's off-limits.

But then Lina is given a journal that her mom had kept when she lived in Italy. Suddenly Lina's uncovering a magical world of secret romances, art, and hidden bakeries. A world that inspires Lina to follow in her mother's footsteps.

It’s been years since 17-year-old Becca Hart believed in true love. But when her former best friend teases her for not having had a boyfriend, Becca impulsively pretends she’s been secretly seeing someone. Brett Wells has it all. As captain of the football team and one of the most popular guys in his school, he should have no problem finding someone to date, but he’s always been more focused on his future than who to bring to prom.

When band-geek Ivy and her friends get together, things start with a rousing board game and end with arguments about Star Wars. Her older sister Autumn is a different story. Enigmatic, aloof, and tough as nails, Autumn hasn't had real friends - or trusted anyone - in years. Even Ivy. But Autumn might not be tough enough. After a drug deal gone wrong, Autumn is beaten, bound, and held hostage. Now, trapped between life and death, she leaves her body, seeking help. No one can sense her presence - except her sister. When Autumn doesn't come home, Ivy just knows she's in trouble.

Classic movie buff Bailey "Mink" Rydell has spent months crushing on a witty film geek she only knows online by "Alex". Two coasts separate the teens until Bailey moves in with her dad, who lives in the same California surfing town as her online crush. Faced with doubts (what if he's a creep in real life - or worse?), Bailey doesn't tell Alex she's moved to his hometown. Or that she's landed a job at the local tourist-trap museum. Or that she's being heckled daily by the irritatingly hot museum security guard, Porter Roth - a.k.a. her new arch-nemesis.

When seventeen-year-old Bailey starts a new job at a hotel waterpark, she is less than thrilled to see an old acquaintance is one of her coworkers. Bailey met Charlie a year ago on the long flight to Omaha, where she moved after her parents’ divorce. Charlie’s cynicism didn’t mix well with Bailey’s carefully well-behaved temperament, and his endless commentary was the irritating cherry on top of an already emotionally fraught trip. Now, Bailey and Charlie are still polar opposites, but instead of everything about him rubbing Bailey the wrong way, she starts to look forward to hanging out.
