67. Mary Roach on Curiosity, Storytelling, and Her Newest Bestseller / IWAW Author Series
In Walks a WomanShow Notes
Mary Roach has created a nonfiction writing lane all her own, and in her 8th book, she embarks on a world-wide tour of the scientific quest to replace pretty much every part of the human body.
Her book, REPLACEABLE YOU, came out this month--April 2026--and it's already a bestseller. While she was visiting Lawrence, Kansas, on a trip sponsored by the Lawrence Public Library, Mary sat down with Sonja and Vanessa for an interview about her new book, her writing journey, and Mary shares an exclusive scoop on her plans for her next project!
Mary recounts some of her research and travel adventures from writing Replaceable You. Important questions are answered: Should you spontaneously volunteer your body for scientific experimentation? How do you cold call someone about spending a night in their iron lung? Where should you take a urologist to dinner?
IWAW also explores how Mary Roach became, well, MARY ROACH. For example, if you assumed Mary was a STEM major, you’d be wrong. What did determine her academic course? How did she get into writing? What writers did she love? How does she know what’s funny enough to make it into a “Mary Roach” book?
Along the way, Sonja segues via a blind lemon, Vanessa auditions to be Mary's audiobook laugh track, and Mary finds out there are way fewer than 6 degrees of separation between herself and Sonja.

Women make up half the population, but only about 28% of Congress. What would change if more women held office? At In Walks a Woman, we believe stories shape reality, and if we change the stories, we can change who gets a voice. This episode asks what happens when we rewrite one of the biggest stories of all: who represents us.
Our guests today have just released two eye-opening books! In Swiftynomics: How Women Mastermind and Redefine Our Economy, economist Misty Heggeness uses the stories of trailblazers like Taylor Swift to reveal how everyday American women shape the economy, often in ways the numbers never capture. In A Gun of Her Own: The Everyday Lives of Women Who Shoot, sociologist Margaret S. Kelley shows that for many women, a gun is about more than protection; it's a symbol of independence and control over their own lives.

Clay Wirestone, award-winning opinion editor at the Kansas Reflector, was so generous to join us in studio for a great interview about his new book, Opinionated: Kansas Journalists Who Proved Why Commentary Matters — Then and Now, published by the University Press of Kansas. In his impressive tour of Kansas journalism from the 1920s to the 1970s, Clay honors some truly remarkable women who helped build and sustain their communities through their writing. Clay shares wonderful details about Mamie Boyd of Mankato, Zula Bennington Greene of Topeka, Donna Burough Opat of Lindsborg, and Lucile Bluford, who edited the Kansas City Call. We talk about a time when newspapers were truly local, and the people writing them were deeply woven into the lives of their towns. These women wrote about their neighbors, their politics, and their daily lives, and much of that writing has been lost, buried in the archives of small towns, some of which are nearly ghost towns today. Clay's book brings their words back into the light. Kansas is remarkable for so many reasons, and its legacy of fearless local opinion writing is one of them. As an opinion writer himself, Clay isn't studying the craft from the outside. He explores these columnists with the insight of someone who knows exactly what it takes to put your opinions in print, week after week, for the community you call home.
