“Wonderful…To spend 300-plus pages with Heiny’s wry voice and colorful cast of characters is to love them, truly. An amusingly engaging take on long-term marriage with a lovably loopy character at its center.”

—Kirkus (Starred Review)

“Audra Daltry is a singular creation—a character so funny, so appealing, so sure that she can change the world for her family that she will jump right off the page and take up permanent residence in your heart. Standard Deviation is a marvel.”

—Kate Atkinson, author of Life After Life 

Standard Deviation is a winning effort that smartly examines the ties that bind in even the most unlikely of marriages…Heiny’s gift for quick-witted dialogue displays the skill of an observational comic.”

—Shelf Awareness

A divinely funny novel from the celebrated author of Single, Carefree, Mellow about the challenges of a good marriage, the delight and heartache of raising children, and the irresistible temptation to wonder about the path not taken.

When Graham Cavanaugh divorced his first wife it was to marry his girlfriend, Audra, a woman as irrepressible as she is spontaneous and fun. But, Graham learns, life with Audra can also be exhausting, constantly interrupted by chatty phone calls, picky-eater houseguests, and invitations to weddings of people he’s never met. Audra firmly believes that through the sheer force of her personality she can overcome the most socially challenging interactions, shepherding her son through awkward playdates and origami club, and even deciding to establish a friendship with Graham’s first wife, Elspeth.  Graham isn’t sure he understands why Audra longs to be friends with the woman he divorced. After all, former spouses are hard to categorize—are they enemies, old flames, or just people you know really, really well? And as Graham and Audra share dinners, holidays, and late glasses of wine with his first wife he starts to wonder: How can anyone love two such different women? Did I make the right choice? Is there a right choice? A hilarious and rueful debut novel of love, marriage, infidelity, and origami, Standard Deviation never deviates from the superb.
