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.

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.

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. 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.

Until the day her secret letters are mailed, and suddenly, Lara Jean’s love life goes from imaginary to out of control.

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.

As her college decision looms, Rosa collides - literally - with Alex Aquino, the mysterious boy with tattoos of the ocean whose family owns the marina.
