12 Summer Thriller Books Perfect for Summerween – July 2026 TBR Book List

How far would you run to escape your past?

Venice Beach, Los Angeles. A paradise on earth.

Tourists flock to the Golden Coast and the promise of Hollywood.

But for eight strangers at a beachfront hostel, there is far more on their minds than an extended vacation.

All of them are running from something. And they all have secrets they’d kill to keep…

Sydney Lowe’s life in New York is shattered when her husband, Curtis, admits to a meaningless affair with a client. Begging for forgiveness and vowing to prove his devotion, Curtis suggests the couple retreat to a remote hilltop house in Spain to repair their marriage.

High above the Mediterranean, Sydney and Curtis are working on the isolated property and their relationship when a pair of Australian travelers turns up at their door in dire need of help. Lonely for companionship and desperate for free labor, Sydney and Curtis invite the attractive young couple to stay. But as the days pass, dark secrets come to light, the Lowes’ bond is tested, and not everyone will leave the villa alive.

Jennifer Thorne skewers all-too-familiar family dynamics in this sly, wickedly funny vacation-Gothic. Beautifully unhinged and deeply satisfying, Diavola is a sharp twist on the classic haunted house story, exploring loneliness, belonging, and the seemingly inescapable bonds of family mythology.

Anna has two rules for the annual Pace family destination vacations: Tread lightly and survive.

It isn’t easy when she’s the only one in the family who doesn’t quite fit in. Her twin brother, Benny, goes with the flow so much he’s practically dissolved, and her older sister, Nicole, is so used to everyone—including her blandly docile husband and two kids—falling in line that Anna often ends up in trouble for simply asking a question. Mom seizes every opportunity to question her life choices, and Dad, when not reminding everyone who paid for this vacation, just wants some peace and quiet.

The gorgeous, remote villa in tiny Monteperso seems like a perfect place to endure so much family togetherness, until things start going off the rails—the strange noises at night, the unsettling warnings from the local villagers, and the dark, violent past of the villa itself.

An exclusive thriller writer’s retreat hosted on a private island turns lethal when one of the authors is found murdered in this twisty locked room mystery.

When renowned anonymous author J. R. Alastor hires former aspiring writer Mila del Angél to host a writing retreat at his private manor off the coast of Maine, she jumps at the chance—particularly since she has an ax to grind with one of the invitees. The guest list? Six thriller authors, all masters of deceit, misdirection, and mayhem.

Confess the crimes, survive the tropes.

Alastor and Mila have masterminded a week of games, trope-fueled riddles, and maybe a jump scare or two—the perfect cover for Mila to plot a murder of her own. But when a guest turns up dead—and it’s not the murder she planned—Mila finds herself trapped in a different narrative altogether.

One by one, you’ll lose your turn.

With a storm cutting off the island, and the body count rising, Mila must outwit a killer who knows literally every trick in the book.

Until only one of us remains…

It was supposed to be the party of the century: miles of idyllic white sand beaches, lush jungle foliage…and a dark legend nobody dreamed might be all too true.

When an online influencer and several hundred of his most loyal fans land on Prosperity Island, the plan is simple: five days of elaborate games, drinking, and suntanned fun.

A week in paradise should have been a welcome respite. The only survivor of an infamous cult, Ruth wants nothing more than to keep her head down and not draw attention. She’s spent decades outrunning her blood-soaked childhood, and her identity is a closely held secret.

But then the true history of the island is revealed…along with its sinister connection to Ruth’s past. As guests go missing and games turn deadly, Ruth and the rest of the attendees are forced to question whether they’ve really been invited to paradise…or whether something much darker―and far bloodier―is waiting for them just beyond the bonfire’s light.

On a creepy island where everyone has a strange obsession with the year 1994, a newcomer arrives, hoping to learn the truth about her son’s death–but finds herself pulled deeper and deeper into the bizarrely insular community and their complicated rules…

Clifford Island. When Willow Stone finds these words written on the floor of her deceased son’s bedroom, she’s perplexed. She’s never heard of it before, but soon learns it’s a tiny island off of Wisconsin’s Door County peninsula, 200 miles from Willow’s home. Why would her son write this on his floor? Determined to find answers, Willow sets out for the island.

After a few days on Clifford, Willow realizes: this place is not normal. Everyone seems to be stuck in a particular day in 1994: they wear outdated clothing, avoid modern technology, and, perhaps most mystifyingly, watch the OJ Simpson car chase every evening. When she asks questions, people are evasive, but she learns one thing: close your curtains at night.

High schooler Lily Becker has lived on Clifford her entire life, and she is sick of the island’s twisted mythology and adhering to the rules. She’s been to the mainland, and everyone is normal there, so why is Clifford so weird? Lily is determined to prove that the islanders’ beliefs are a sham. But are they?

Five weeks after Willow arrives on the island, she disappears. Willow’s brother Harper comes to Clifford searching for his sister, and when he learns the truth–that this island is far more sinister than anyone could have imagined–he is determined to blow the whole thing open.

If he can get out alive…

Naomi Shaw used to believe in magic. Twenty-two years ago, she and her two best friends, Cassidy and Olivia, spent the summer roaming the woods, imagining a world of ceremony and wonder. They called it the Goddess Game. The summer ended suddenly when Naomi was attacked. Miraculously, she survived her seventeen stab wounds and lived to identify the man who had hurt her. The girls’ testimony put away a serial killer, wanted for murdering six women. They were heroes.

For decades afterward, the friends have kept a secret worth killing for. But now Olivia wants to tell, and Naomi sets out to find out what really happened in the woods―no matter how dangerous the truth turns out to be.

Ten years ago, Abigail Lovett fell into a job she loves, managing The Passage Inn, a cozy, upscale resort nestled in the North Carolina mountain town of Cutter’s Pass. Cutter’s Pass is best known for its outdoor offerings—rafting and hiking, with access to the Appalachian Trail by way of a gorgeous waterfall—and its mysterious history. As the book begins, the string of unsolved disappearances that has haunted the town is once again thrust into the spotlight when journalist Landon West, who was staying at the inn to investigate the story of the vanishing trail, then disappears himself.

Abby has sometimes felt like an outsider within the community, but she’s come to view Cutter’s Pass as her home. When Landon’s brother, Trey, shows up looking for answers, Abby can’t help but feel the town closing ranks. And she’s still on the outside. When she finds incriminating evidence that may bring them closer to the truth, Abby soon discovers how little she knows about her coworkers, neighbors, and even those closest to her.

Megan Miranda brings her best writing to The Last to Vanish, a riveting thriller filled with taut suspense and shocking twists that will keep you guessing until the very end.

WILL THIS BE THE BEST WEEK OF THEIR LIVES… OR THE LAST?

JULIA, DAVID, AND ERIKA grew up together, spending summers at their idyllic Vermont lake homes for as long as they can remember. Now adults—with their own sullen teens, endless mortgages, and low-voltage sex lives—the three friends have amassed secrets over the years.

This summer, David is eager to show off his newly renovated home—which now blocks his friends’ cherished lake views—and his much-younger girlfriend. He also, unwittingly, brings a nanny with a hidden agenda. What could possibly go wrong?

When David’s girlfriend mysteriously vanishes after a shouting match, Julia and Erika wonder just how well they know their lifelong friend. The lake harbors a harrowing two young women, with no known connection, who vanished without a trace thirty years ago. Did the lake take another?

As a search is mounted, an intricate web of lies, deceits, and betrayals spanning generations starts to surface, and everyone finds themselves in danger of becoming the next victim. Of the lake, or something darker.

Welcome to Wonderland. 

By day, it’s a magical place boasting a certain retro charm. Excited children, hands sticky with cotton candy, run frenetically from the Giant Octopus ride to the Spinning Sombrero, while the tinkling carnival music of the giant Wonder Wheel—the oldest Ferris wheel in the Pacific Northwest—fills the air. But before daybreak, an eerie feeling descends. Maybe it’s the Clown Museum, home to creepy wax replicas of movie stars and a massive collection of antique porcelain dolls. Or maybe it’s the terrifyingly real House of Horrors. Or…maybe it’s the dead, decaying body left in the midway for all the Wonder Workers to see.

Vanessa Castro’s first day as deputy police chief of Seaside, Washington, is off to a bang. The unidentifiable homeless man rotting inside the tiny town’s main tourist attraction is strange enough, but now a teenage employee—whose defiant picture at the top of the Wonder Wheel went viral that same morning—is missing. As the clues in those seemingly disparate crimes lead her down a mysterious shared path of missing persons that goes back decades, she suspects the seedy rumors surrounding the amusement park’s dark history might just be true. She moved to Seaside to escape her own scandalous past, but has she brought her family to the center of an insidious killer’s twisted game? Acclaimed author Jennifer Hillier’s bone-chilling thriller is masterful and fast-paced, hurtling toward a shocking, bloody conclusion.

Since the 1970s, FantasticLand has been the theme park where “Fun is Guaranteed!” But when a hurricane ravages the Florida coast and isolates the park, the employees find it anything but fun. Five weeks later, the authorities who rescue the survivors encounter a scene of horror. Photos soon emerge online of heads on spikes outside of rides and viscera and human bones littering the gift shops, breaking records for hits, views, likes, clicks, and shares. How could a group of survivors, mostly teenagers, commit such terrible acts?

Presented as a fact-finding investigation and a series of first-person interviews, FantasticLand pieces together the grisly series of events. Park policy was that the mostly college-aged employees surrender their electronic devices to preserve the authenticity of the FantasticLand experience. Cut off from the world and left on their own, the teenagers soon form rival tribes who viciously compete for food, medicine, social dominance, and even human flesh. This new social network divides the ravaged dreamland into territories ruled by the Pirates, the ShopGirls, the Freaks, and the Mole People. If meticulously curated online personas can replace private identities, what takes over when those constructs are lost?

FantasticLand is a modern take on Lord of the Flies meets Battle Royale that probes the consequences of a social civilization built online.

Seven authors enter the manor

Can they survive the story within?

When legendary horror author Mortimer Queen passes, a group of writers finds themselves invited to his last will and testament reading, expecting a piece of his massive fortune. Each have their own unique connection to the literary icon, some known, some soon to be discovered, and they’ve been waiting for their chance to step into the author’s shoes for some time.

Instead, they arrive at his grand manor and are invited to play a game. The rules are simple: solve the riddle and progress to the next room. If they don’t, the manor will take one of them for itself.

You see, the Queen estate was built on the bones of Mortimer’s family, and like any true horror story, the house is still very, very hungry.

With the clever, locked-room thrills of Everyone in My Family Has Killed Someone with the ghostly horror of The Fall of the House of Usher, How to Survive a Horror Story is a bright, biting, thrill-ride that begs us to contemplate how the best horror stories come to be.
