The House Swap

Keri Beevis

Suspense, Psychological Thriller • Sep 1, 2026

Desperate for a quiet escape, I arranged a home swap with Tom—a man I thought I knew—and fled to his secluded villa in Crete alongside my best friend, Keira. It was supposed to be a sanctuary of winter sun and silent, empty beaches. At last, room to breathe.
Then Keira vanishes without a word.
Suddenly, paradise feels like a trap. The neighbors watch me with unearned familiarity. The handyman lingers in the shadows. Doors I secured swing open, and objects subtly shift when I’m not looking. I try to blame exhaustion and stress, but the mounting dread is impossible to ignore.
Isolated and questioning my own sanity, one terrifying truth remains: I am a long way from home, and I need to escape before the trap snaps shut.

The House Swap throws you straight into the deep end, told almost entirely from Poppy’s perspective in the present day. The story moves at a fast pace, broken up into medium-sized chapters. The setting adds a heavy layer of tension. Poppy is staying in a gigantic villa in Greece, and that sheer size and isolation really amplifies her paranoia. I spent a large amount of the book trying to decide if she was losing her mind or if there was a calculated conspiracy against her. I could not figure out the truth until the final pieces fell into place.
The twist is a good one. It caught me off guard and shifted the narrative in a way that made all the previous anxiety feel justified. My only real gripe is the final stretch. After such a suspenseful ride, the ending felt a little too abrupt. The fates of certain characters were just settled in a few rushed lines, rather than giving them a proper wrap-up or even leaving things intentionally ambiguous. Still, the psychological manipulation and that striking Greek setting kept me hooked.
If you like isolated foreign settings, intense paranoia, and surprising twists, then you will enjoy this book.

Xavier Bradshaw: Ghostwriter

W.M. Lessman

Mystery, Psychological Thriller, Crime • Sep 15, 2026 • Series: Xavier Bradshaw Crime Files #1

Two decades after a string of brutal, unsolved murders haunted Livingston, Alberta, the nightmare has returned. A city councilor is discovered crucified in a local church, and a young woman’s body is left abandoned by the river. Investigative reporter Xavier Bradshaw and his new partner, Jessi, plunge into these macabre echoes of the past—only to find the evidence pointing squarely at Xavier himself.
With the local police eager to close the case and lock him away, Xavier races to uncover the truth. His prime suspect? His own mentor, a renowned horror author whose obsession with the killings borders on the sinister. Time is running out, and if Xavier doesn't unmask the true killer soon, his final byline might be his own obituary.

W.M. Lessman brings a refreshing dynamic to the investigative protagonist with his character Xavier Bradshaw. As an ex-cop turned reporter, Xavier operates with the sharp mind of a detective but without the red tape of law enforcement. He isn't much of a rogue wildcard yet, but staying grounded makes him a solid anchor for the story, and I am curious to see if his personality develops in that direction as the series continues. The supporting cast adds a lot of value too, particularly Stephanie and Bobby, who are great side characters and really help Xavier and Jessi bond with each other.
The story has a slower pace, but it never drags or gets boring. Momentum stays alive thanks to the short chapters, and the author’s wonderful writing. There is a sizable cast to keep track of, but the background provided for each major player is distinct and thorough enough that I never felt lost or confused about who was who.
This leans much more into traditional suspense and mystery territory rather than a high-octane thriller. It builds to a genuinely good twist. The ending, however, wrapped up quickly, leaving the fates of some characters rather vague.
If you like character-driven mysteries, ex-cop protagonists, and methodical pacing, then you will enjoy this book.

The Christmas Guest

B P Walter

Suspense, Mystery, Psychological Thriller • Sep 18, 2026

On Liars Island, Christmas dinner is a meticulously staged affair. Beneath the sparkling decorations and the clinking of wine glasses, the family’s forced smiles hide a multitude of sins. For years, they've perfected the art of avoidance, especially when it comes to the unspoken tragedy of six Christmases past: the night their mother died.
But this year, an uninvited ghost from the past crashes the reluctant reunion. He’s asking questions, too many questions, about that terrible night. His presence cracks open old wounds and threatens to expose the meticulously guarded truths everyone thought were buried forever.
As a relentless storm rages, isolating them completely on the island, the veneer of festive cheer shatters. Trapped with a stranger who knows too much and a family riddled with secrets, the festive celebration turns into a chilling interrogation. Is the real danger the storm outside, the relentless guest, or the deadly truths lurking within their own blood?

A Christmas setting can add an extra layer of tension to a thriller, but this one never came together for me. The story moves between Marguerite’s perspective in the past and multiple perspectives in the present, gradually revealing how the past connects to the events unfolding at the house. There were a few well-executed twists along the way, and I appreciated how the different timelines slowly filled in the bigger picture.
My biggest issue was that the story was slow from beginning to end. I also struggled to connect with the characters. None of them were particularly likable, and the triplets were so unpleasant, even toward each other, that it was difficult to become invested in their relationships. Noah came across as awkward and bumbling throughout, while Cliff was an especially difficult character for me. Although he is thirty-one, the way he was written often made him seem much younger, and I found that characterization distracting.
I also felt like several subplots didn’t add much to the overall story. Noah’s relationship with his stepsister, Ruby, along with the smaller storylines involving Alistair and Dylan, felt more like filler than meaningful additions to the mystery. Instead of building tension or developing the characters in a satisfying way, they slowed the story even further.
There were moments where the mystery pulled me back in, particularly when some of the twists were revealed, but they weren’t enough to overcome the slow pacing or my lack of investment in the characters. The ending also felt rushed and ultimately unsatisfying, leaving me wishing the story had spent less time on unnecessary detours and more time delivering a stronger payoff.
If you like dual timelines, dysfunctional families, and Christmas-set thrillers, then you may enjoy this book. #NetGalley #TheChristmasGuest

Thank you to BookSirens for an advanced copy of this book.

The premise pulled me in right away, and the short chapters kept the pacing brisk early on but a promising setup can only carry a story so far when the focus shifts so drastically mid-plot. The writing itself is decent, and the first half delivers an entertaining mystery that had me speculating about where the narrative was headed.
But instead of doubling down on the suspense, the story takes a sharp detour. By the time I reached part three, the momentum ground to a halt. I was expecting a deep dive into the investigation, but the plot shifted heavily to Lydia and Vladislav. It is not that their dynamic feels out of place, but the sheer volume of their romantic scenes drags everything down. There is far more romantic tension and sex here than actual sleuthing. I steer clear of romance, so watching what was supposed to be a thriller morph into one was a frustrating pivot.
After so much early build-up, the lack of an investigative payoff makes the ending very unsatisfying. I can’t say specifics without verging into spoilers but I did not get the decent ending I was hoping for after struggling to finish this book.
If you like a messy romance with your mystery then you may enjoy this book.
