If you found K.L. Walther the way most people did, through The Summer of Broken Rules on your For You page or pinned to somebody’s summer TBR, you probably assumed she’d written one perfect Martha’s Vineyard book and that was that. Then you finished it, went looking for more, and discovered the situation is better and slightly more complicated than expected. So here’s the actual answer to searching KL Walther books in order: eight novels, technically all standalones, secretly all connected. Characters wander between books like it’s one big summer town, which means the order you read them in genuinely changes the experience.
Let’s sort it out properly.
The publication order first, since it’s the cleanest way through: If We Were Us (2020), The Summer of Broken Rules (2021), Maybe Meant to Be (2022), What Happens After Midnight (2023), While We’re Young (2025), A First Time for Everything (2025), We’re a Bad Idea, Right? (2026), and The Summer of Second Chances (2026). If you’re a completionist, just read them in that sequence and skip to the end of this post. For everyone else, here’s what each one is and who it’s for.
If We Were Us
If We Were Us is the debut, set at the Bexley School, the boarding school her later books keep orbiting. Everyone on campus assumes best friends Sage and Charlie will end up together. Charlie knows why they won’t: he’s drawn to Luke, the new boy, and hasn’t figured out how to say so out loud. It’s a gentler, more earnest book than her later ones, about the gap between the story people tell about you and the one you’re living. Start here if you like watching an author find her voice in real time.

The Summer Of Broken Rules
The famous one that earns it’s reputation. Meredith Fox, still grieving her sister, arrives on Martha’s Vineyard for a family wedding and gets pulled into the family’s giant game of Assassin. The game gives the grief somewhere to go, which is the book’s quiet genius, and Wit, her competition, is one of the most likeable love interests in YA. If you only read one Walther, it’s this. If you read this one first, welcome, that’s the standard entrance.

Maybe Meant To Be
Maybe Meant To Be returns to Bexley and to Sage, who finally gets her own story alongside Charlie’s twin brother Nick, while Charlie and Luke’s relationship deepens in parallel. It rewards reading If We Were Us first, though it stands alone if you’re stubborn. This is the book where the connected-universe thing becomes visible, and half the fun is watching background characters you already know walk through scenes.

What Happens After Midnight
What Happens After Midnight is the senior-prank book: one last elaborate boarding school night, an ex who’s suddenly very present again, and the specific ache of endings you chose but still mourn. It’s the most contained of her books, one night doing the work of a whole summer. Read it when you want Walther’s feelings in a shorter timeframe.

While We’re Young
While We’re Young is Walther’s Ferris Bueller book, and she’s open about it. Three friends whose tangled love lives have quietly wrecked the group dynamic get one unsanctioned senior skip day in Philadelphia to fix it, which requires kidnapping one of them. It’s structured like a caper and lands like a friendship story. The romance is there, but the group is the love interest.

A First Time for Everything
This book follows Madeline, cornered during a bridesmaids’ game of Truth or Dare into admitting she’s never been kissed, which mobilizes the entire bridal party into finding her a wedding date. Disastrous dates ensue, obviously, while the real answer sits next door the whole time. This is also where Connor first appears, which matters more than you’d think for what comes later.

We’re a Bad Idea, Right?
We’re a Bad Idea, Right? is the 2026 fan-service book in the best sense. Audrey, eighteen years of perfect behavior deep, starts dismantling her rule-following life via a fake-dating scheme with her best friend Henry and a very unauthorized plan involving her family’s Connecticut mansion. Walther threads in familiar faces from almost every earlier book, including Meredith, Wit, and the Assassins game itself. Readable alone, but it’s a reunion episode, and reunions hit harder when you know the guests.

The Summer of Second Chances
The Summer of Second Chances is the newest, and the closest she’s come to a true companion to Broken Rules. Olivia stays home while her friends leave for college, because her grandmother Annie has dementia and Olivia can’t imagine being far away. A box of Annie’s old photos pulls her to Martha’s Vineyard to retrace her grandmother’s summers, where Connor, from A First Time for Everything, is waiting to be part of her present. It’s about memory, letting go, and the island doing what the island does. Bring the tissues you didn’t need for the others.

So, the recommended order, if you want the connections to land: If We Were Us, Maybe Meant to Be, The Summer of Broken Rules, A First Time for Everything, then We’re a Bad Idea, Right? and The Summer of Second Chances, with What Happens After Midnight and While We’re Young slotted anywhere, since they float free.
And if you’re here as an Emily Henry or Abby Jimenez reader wondering whether YA can possibly scratch that itch: this is the crossover author. The banter is there, the summers are there, the grief under the sweetness is there. The only thing missing is the spice, and honestly, by chapter three you won’t be keeping score.
Eight books, one interconnected summer world, and an author who clearly plans to keep building it. Reading in order isn’t required. It’s just the difference between visiting and belonging.
