Katherine Heiny’s ‘Standard Deviation’ is a sharp, tender, and irresistibly funny novel that explores the chaos and charm of modern family life. At the heart of the story is Graham Cavanaugh, a reserved, contemplative man navigating marriage to Audra, his vivacious and unpredictable second wife. Audra’s energy is infectious—she speaks to everyone, makes impulsive decisions, and fills their New York apartment with a rotating cast of guests and activities. Graham, calmer by nature, finds himself both enchanted and exhausted by her, slightly questioning the choices that brought him here.

Together, they raise their 10-year-old son, Matthew, who has Asperger’s syndrome and a deep passion for origami. Parenting, in this context, is portrayed with both humour and honesty, as Heiny captures the complex emotions that come with trying to support a neurodivergent child in a world that doesn’t always make space for difference. Through playdates, paper-folding clubs, and awkward social events, Graham and Audra must constantly reevaluate what “normal” means for their family, often guided by Audra’s exuberance and Graham’s quiet longing for calm. 

What elevates ‘Standard Deviation’ beyond a domestic comedy is its exploration of identity, nostalgia, and the enduring pull of the past. As Graham crosses paths with his poised and distant first wife, the novel delicately examines the idea of the “road not taken.” Through brilliantly drawn characters and sly, observational humour, Heiny invites readers to reflect on the messy, funny, and sometimes painful contradictions that make up long-term relationships. I found it particularly endearing in the way it portrays real life, full of imperfections, awkwardness, and tenderness, with a domestic world that feels authentic and relatable. The contrast between Graham and Audra’s personalities is both funny and touching, and the way their son’s Asperger’s is framed not as a standalone storyline but as a part of their everyday rhythm adds a layer of emotional truth and relevance. It's a novel that lingers like a fond memory, equal parts hilarious and deeply human.
