In fact, it’s in her blood - according to family legend, her too-many-greats-to-count-grandmother once danced for the Paris Opera and was painted by Degas himself! Her parents say it’s just a fantasy, but to Mia it’s so much more than that. It’s her fate.

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.

Jayne and June Baek are nothing alike. June’s three years older, a classic first-born, know-it-all narc with a problematic finance job and an equally soulless apartment (according to Jayne). Jayne is an emotionally stunted, self-obsessed basket case who lives in squalor, has egregious taste in men, and needs to get to class and stop wasting Mom and Dad’s money (if you ask June). Once thick as thieves, these sisters who moved from Seoul to San Antonio to New York together now don’t want anything to do with each other. That is, until June gets cancer.

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.

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.

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.)

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.

Emma Saylor doesn’t remember a lot about her mother, who died when Emma was 12. But she does remember the stories her mom told her about the big lake that went on forever, with cold, clear water and mossy trees at the edges. Now, it’s just Emma and her dad, and life is good, if a little predictable...until Emma is unexpectedly sent to spend the summer with her mother’s family, whom she hasn’t seen since she was a little girl.

Sixteen-year-old Lara Jean Song keeps her love letters in a hatbox her mother gave her. They aren’t love letters that anyone else wrote for her; these are ones she’s written. One for every boy she’s ever loved - five in all. When she writes, she pours out her heart and soul and says all the things she would never say in real life, because her letters are for her eyes only. Until the day her secret letters are mailed, and suddenly, Lara Jean’s love life goes from imaginary to out of control.

Avery has always used music as an escape. But after her best friend betrays her, even her perfectly curated playlists can't help her forget what happened. To make matters worse, her parents have dragged her and her social-media-obsessed sister to a remote family camp for two months of "fun". 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.

The first time I met Hudson Rothschild was at a wedding. I’d received an unexpected invitation to one of the swankiest venues in the city. Hudson was a groomsman and quite possibly the most gorgeous man I’d ever laid eyes on. He asked me to dance, and our chemistry was off the charts. I knew it wasn’t a good idea to get involved with him, considering the wedding I was at. But our connection was intense, and I was having a great time. Though the fun came to a screeching halt when Hudson figured out I wasn’t who I’d said I was.

Everything about Jessie is wrong. At least that's what it feels like during her first week of junior year at her new ultra-intimidating prep school in Los Angeles. Just when she's thinking about hightailing it back to Chicago, she gets an email from a person calling themselves Somebody/Nobody (SN for short), offering to help her navigate the wilds of Wood Valley High School. Is it an elaborate hoax? Or can she rely on SN for some much-needed help?
