The Housewife by Natalie Barelli

The perfect housewife story turning into a nightmare sounds so addictive.

From bestselling indie thriller writer Natalie Barelli comes a new deliciously dark novel about a woman who married the man of her dreams, only for him to become her worst nightmare.

Jodie always dreamed of being a housewife. And after a whirlwind romance, she marries renowned psychologist Dr. Roy Davies and moves into his perfect Beverly Hills home. But the fairy tale fades fast. Roy is distant, his friends view her as a gold-digger, and the house still reveres his late wife, Deborah, whose presence still looms over everyone and everything.

When Jodie learns Deborah became a recluse before death, she begins to suspect Roy was behind it. And the deeper she digs, the darker Roy’s past appears―obsessive, controlling, unfaithful. Increasingly convinced he had something to do with Deborah’s death, Jodie knows she should go to the police, but that would require revealing her own secret. A secret that could destroy her.

But Jodie won’t be silenced. Because the truth about Roy is worse than she imagined―and now, trapped in a house built on lies, she must find a way out before she becomes the next perfect wife to vanish.

It Could Have Been Her by Lisa Jewell

It Could Have Been Her sounds mysterious and creepy in the best way. A missing girl, a strange house, and secrets from the past are exactly the kind of thriller I like.

#1 New York Times bestselling author Lisa Jewell brings her signature dark, atmospheric suspense and sharp acuity to this new psychological thriller about a lost dog, a missing woman, and a mysterious house.

The teenaged girl that had been staying nearby with the dog is nowhere to be found, and Jane decides to return the dog to his registered owner hours away in London, in the deepest backwaters of Hampstead. But when Jane arrives, she is immediately unsettled—because Jane has a dark history with this house

The man who answers the door tells her the dog, Hugo, must have been stolen from the Heath, but Jane very much doubts that is true. Through the window, she catches a glimpse of a haunted-looking woman, not the missing girl she’d hoped to find.

The Unknown by Riley Sager

The Unknown sounds so creepy and fun. An island with disappearances and strange things happening at night already has me interested.

In 1926, five women disappeared from a remote island in Vermont. Now, one hundred years later, it’s happening again.

Struggling actress Marin Keane is shocked when she lands a role in a major motion picture about the unsolved mystery of New Avalon, an island on sprawling Lake Faraday in Vermont. She’s even more surprised when she learns that the role requires a weeklong research trip to that very spot.

Because New Avalon isn’t your ordinary island. A century ago, it was a commune for spiritual mediums—until they all vanished in 1926. The only trace of them was five dresses hanging from the branches of an old oak tree in the middle of the island, one for each missing woman. Some locals say they simply left. Others think they were murdered. But the prevailing opinion, thanks to a diary left behind by one of the vanished, a young woman named Daisy Rue, is that a séance gone wrong conjured something supernatural that took them all one by one.

Not long after arriving, Marin and her castmates, including legendary actress Violet Wright and white-hot director Ronan Peters, begin to realize all is not right with New Avalon. They hear strange noises in the night and notice mysterious symbols left behind by the island’s previous occupants. And after a sudden health emergency leaves Marin, Ronan, and the other actors stranded on the island, the disappearances begin again.

Is it the work of someone trying to derail the movie? Or is the island’s alleged supernatural past catching up with the present? As fear and suspicion mount, Marin turns to Daisy’s diary, hoping it holds the key to figuring out what really happened to the women of New Avalon—and how to keep the island’s terrible history from repeating itself.

Freyja by Margrét Ann Thors

Freyja sounds atmospheric and mysterious. I also love books set in Iceland . They always feel cold and haunting.

The unsolved case of a young girl’s disappearance reopens after twenty years in this moody, atmospheric debut of suspense set in Reykjavík and the Icelandic coast.

Unnur has secrets. A single mother to a beloved daughter, Lilja, she lives a deliberately quiet life in Reykjavík, working at a bakery under an assumed last name and pushing away haunting visions of the last summer of her childhood.

Big Little Truths by Liane Moriarty

I’m excited for Big Little Truths because I loved the first book. Seeing the characters older now sounds really fun.

In her first-ever sequel, Liane Moriarty examines the complexities of modern women’s lives, shining light on shame and family secrets with wit and compassion. Whether you’ve read Big Little Lies or not, this is the perfect novel for longtime fans and new readers alike.

The last time we saw the women of Big Little Lies—Madeline, Celeste, Jane, Renata, and Bonnie—their children were five years old. If someone wasn’t invited to a child’s birthday party, feelings were hurt. But ten years have passed, and the kids are now in high school, with all of the drama that accompanies teendom (goodbye playdates, hello drugs, sex, and alcohol).

Now, after the principal of the high school receives a severed human finger in the mail, the parents are in an uproar. But Madeline, Celeste, Jane, Renata, and Bonnie have other things to worry about. Celeste’s mother-in-law, Mary Louise, is behaving oddly—is it old-age forgetfulness and forthrightness, or something more sinister? Madeline is facing perhaps the biggest challenge of her life, Jane is at a dangerous fork in her marriage, Bonnie has realized there’s only so much solace in yoga. And Renata? Renata is living her best life—revenge is sweet.

When a strange man begins lurking around the school asking supposedly innocent questions, this tightly connected group of women must finally face the full repercussions of the big little truths they have and haven’t shared with their kids. Because the stakes are now much higher than not being invited to an ice-skating show—and the ice has never been thinner for any of them.

Heart of Glass by Jennifer Hillier

Heart of Glass looks like the kind of thriller that keeps getting darker. I really love small-town secrets and old murder cases.

A serial killer recants his long-ago confession regarding a small-town high school girl―and her then-best friends are forced to confront what really happened that night and what’s happening now.

Seaside is a small coastal town, known originally for the local amusement park. But twenty-five years ago, a serial killer dubbed The Carnival Killer confessed to the murder of a local high school girl. Now, he’s recanted that confession.

Barb, Nicolette, and Lorelei were best friends – then they met “Sam” at Wonderland, the local amusement park. After hanging out with him there, and accompanying him to the drive-in movie, where the twenty-something handsome drifter made out with Lorelei in the backseat. That night was the last time Lorelei was seen alive, her murdered body surfacing a couple of days later in a local cranberry bog.

Barb’s dreams of leaving Seaside and becoming a successful writer never materialized and she is a freelancer for the local newspaper and, secretly, writes anonymously about reality tv stars for a hugely successful gossip web-site called Reality Bitch. Specifically, she writes savagely about a long-running show set in Canada called Trophy Wives.

Nicolette left town shortly after Lorelei’s body surfaced, never to return. Ultimately, she married a very rich man, moved to Toronto and rebranded herself as Cole Lennox, one of the stars of Trophy Wives.

With the amusement park about to reopen, revitalizing the dying town of Seaside, the Carnival Killer recants his confession about killing Lorelei, the dead body of young woman washes ashore, and the truth about what happened that night twenty-five years ago – and what is happening now – threatens not only the carefully constructed lives of Barb and Nicolette, but the very fabric of Seaside itself.
