It's ideal for those who enjoy twisty narratives that explore what truly defines family bonds beyond biology.

The Stranger in My Home became a Number One eBook Bestseller and delivers a gripping domestic thriller with unexpected twists. Readers praise Parks for creating palpable tension while keeping character reactions realistic rather than melodramatic. The novel features a clever double-meaning title that becomes clear by the ending, and the plot maintains suspense even when readers suspect certain developments. The exploration of switched-at-birth consequences feels fresh and emotionally authentic, making it a worthwhile read for thriller fans.

The major twist reveals that Tom Truby, who presents himself as a devoted widowed father, is actually a dangerous manipulator on drugs. His wife Annabel is alive—they divorced a year ago, and her breast cancer wasn't hereditary as Tom claimed. Tom deliberately sabotaged Olivia's relationship with Alison by lying that her biological mother didn't want her. The climax involves Tom kidnapping Katherine and holding her drugged in a Brighton basement, where Alison must play along before knocking him down stairs to escape.

The Stranger in My Home examines whether biology or upbringing defines parent-child bonds through Alison's relationships with both daughters. Katherine, raised by Alison but not biologically hers, remains the center of her world despite the revelation. Meanwhile, Olivia, Alison's biological daughter, mirrors many of her mother's characteristics yet remains hostile and distant. The novel questions what truly makes someone a parent—genetics or fifteen years of daily love and sacrifice—while exploring how both girls process their fractured identities.

Alison rescues Katherine from Tom's basement in Brighton after he kidnaps her, saving her daughter by pretending to cooperate before physically overpowering him. The revelation of Tom's lies, drug addiction, and manipulation comes through his ex-wife Annabel, who exposes his schemes. The families must rebuild after Tom's arrest, with Alison having proven her devotion to Katherine transcends biology. The resolution addresses how trauma reshaped everyone involved while emphasizing that love, not genetics, ultimately defines family.

Parks structures the narrative in first-person present tense through Alison's perspective, creating immediacy and emotional intensity. She marks time with seasonal events like autumn walks, ice hockey matches, and Bonfire Night, showing the slow unraveling of normal family life. The author employs "enough misdirection" to keep readers uncertain about key plot developments even when suspicions form. Character reactions remain plausible rather than extreme, which makes the nightmare scenario feel more terrifying because it could happen to any family.

The Stranger in My Home deeply examines family bonds, trust, and identity when biological truth contradicts lived experience. Parks explores maternal instinct and whether motherhood is defined by biology or emotional connection forged through years of caregiving. The novel addresses secrets from the past and how they influence present-day decisions, particularly through Alison's difficult childhood after being abandoned by her mother. Additional themes include manipulation, the masks people wear, and resilience when facing life-altering revelations that challenge everything you believed about your family.

The Stranger in My Home belongs to Parks' domestic noir phase alongside The Image of You, I Invited Her In, and Lies Lies Lies, which all feature twisty psychological elements. Unlike her earlier contemporary romance novels like Playing Away and Young Wives' Tales, this book focuses on suspense and darker family secrets. The novel shares Parks' signature scrutiny of family concepts and parenting but adds thriller elements that intensify the emotional stakes. It demonstrates her evolution from relationship-focused women's fiction to more complex psychological narratives with criminal elements.

The title carries a clever double meaning that becomes fully apparent only at the story's conclusion. Initially, it refers to Olivia, Alison's biological daughter who enters their home as essentially a stranger despite genetic ties. The second meaning points to Tom Truby, who infiltrates their lives under false pretenses while hiding his true dangerous nature. The title also reflects Alison's fear that Katherine, the daughter she raised, might become a stranger once the biological truth is revealed—questioning whether their bond can survive this revelation.

Parks portrays the switched-at-birth revelation with psychological realism, focusing on the devastating emotional aftermath rather than sensationalism. The characters' range of responses—Jeff's withdrawal into writing, Alison's anxiety, Katherine's identity crisis, and Olivia's hostility—feel entirely plausible for such an upheaval. Unlike melodramatic approaches, Parks keeps reactions grounded while building palpable tension through the families' attempts to navigate ice hockey games, fireworks displays, and forced bonding that highlights their fundamental incompatibility. The medical revelation backstory and legal implications reflect authentic complexities of such rare hospital errors.
