Mark Cirino has written and edited many books about Ernest Hemingway, including Reading Hemingway's Across the River and Into the Trees, One True Sentence: Writers and Readers on Hemingway's Art, Ernest Hemingway and the Geography of Memory, Hemingway's Spain, and Ernest Hemingway: Thought in Action. He's the editor for Kent State University Press Reading Hemingway series. He's also the author of two novels, Name the Baby and Arizona Blues. And my favorite, he hosts a podcast called One True Podcast. One of my favorite podcasts out there.
