The Overnight Guest appeals to thriller and mystery fans who enjoy atmospheric, slow-burn suspense with dual timelines. Readers who appreciate rural Iowa settings, snowstorm isolation scenarios, and psychological depth will find this compelling. It's ideal for fans of true-crime narratives, stories exploring trauma and resilience, and those who enjoyed Gudenkauf's previous bestsellers. The book suits readers seeking page-turning tension combined with emotional character development and shocking plot twists.

The Overnight Guest delivers a tightly woven thriller that Catherine McKenzie describes as "guaranteed to raise the hairs on the back of your neck and keep you turning the pages deep into the night". The dual-timeline structure effectively builds suspense while exploring themes of trauma and resilience. The atmospheric Iowa farmhouse setting during a blizzard creates claustrophobic tension that enhances the mystery. Gudenkauf's skillful plotting leads to shocking revelations about the true villain, making it a satisfying read for thriller enthusiasts.

In August 2000, twelve-year-old Josie Doyle and her friend Becky Allen were at the Doyle family farm when gunshots erupted inside the house. Josie's parents were shot point-blank, and when the girls tried to escape into the cornfield, Josie was shot in the arm but managed to flee. Becky was captured and disappeared, with Josie's brother Ethan initially suspected. The girls had snuck out at midnight to jump on the trampoline when they saw flashes in the upstairs window and a man emerged, forcing them to run.

Randy Cutter, not Jackson Henley, is revealed as the true villain behind the murders and Becky's abduction. Randy's sinister intentions and twisted motivations come to light during a confrontation with Wylie, shattering her understanding of the past. This shocking revelation exposes the depths of Randy's manipulation and the danger he poses. The climactic showdown between Wylie and Randy involves a brutal struggle where Wylie, armed only with a hatchet, fights to protect Becky and her daughter.

The Overnight Guest weaves three interconnected storylines: Wylie's present-day stay at the farmhouse during the snowstorm, the 2000 murders involving young Josie and Becky, and Abby Morris's uneasy encounter on a warm August night in 2000. This structure gradually reveals how past and present connect, building suspense as Wylie researches the decades-old crime while experiencing her own danger. The alternating perspectives allow readers to piece together the mystery alongside Wylie, creating layered tension and unexpected revelations about the true perpetrator.

The Overnight Guest explores trauma's lasting impact and how past violence echoes into the present, affecting survivors and communities for decades. Resilience emerges as characters confront evil and fight for survival, with Wylie drawing on inner strength during her final confrontation. The novel examines familial bonds and their enduring power through Becky's reunion with her mother and daughter after captivity. Additional themes include the dangerous pursuit of truth in true-crime writing, isolation's psychological effects, and how secrets contained within physical spaces can haunt those who inhabit them.

The rural Iowa farmhouse serves as both setting and character, its isolated location creating vulnerability during the deadly snowstorm that traps Wylie. Gudenkauf, who sets most novels in her home state, uses Iowa's cornfields, gravel roads, and prairie landscape to establish atmospheric tension. The remote Blake County location amplifies the sense of danger, as characters cannot easily access help. The farmhouse itself becomes haunted by the murders within its walls, with Wylie forced to confront both physical danger and psychological terror in the very place where violence occurred.

Becky Allen was twelve years old when she was abducted during the 2000 Doyle family murders after being separated from her friend Josie in the cornfield. While Josie escaped despite being shot, Becky was captured by Randy Cutter and held for years. The novel culminates in Becky's heartbreaking reunion with her mother Margo and her own daughter after decades of captivity. This emotional reunion brings bittersweet closure as the family grapples with trauma while rebuilding their lives, freed from Randy Cutter's evil.

The Overnight Guest continues Gudenkauf's signature style of atmospheric Midwestern thrillers with psychological depth, similar to her Edgar-nominated debut The Weight of Silence. Like her previous works including Not a Sound and Before She Was Found, this novel explores trauma's aftermath and features Iowa settings that ground the suspense in familiar terrain. The dual-timeline structure and focus on children affected by violence echo themes from These Things Hidden and One Breath Away. Her consistent exploration of resilience and community impact distinguishes her ten-novel thriller catalog.

The Overnight Guest succeeds through its claustrophobic blizzard setting that physically traps Wylie while psychologically confronting her with the house's violent history. The discovery of an unconscious boy in the snow immediately raises stakes and questions about present danger versus past crimes. Gudenkauf's technique of revealing Randy Cutter as the true villain rather than the suspected Jackson Henley delivers a shocking twist that redefines the entire narrative. The tightly woven structure, alternating between vulnerable characters across timelines, maintains relentless tension while building toward the brutal final confrontation.
