This week, host Isaac Butler talks to novelist Julia Hannafin and ecologist Adam Rosenblatt. In the interview, they discuss Julia’s new novel Cascade, which includes information about sharks and other marine life that Adam helped to verify. Julia explains how factual accuracy helped to solidify and drive both the plot of Cascade and some of its emotional power. Adam talks about what the collaborative process was like for him and argues that science is more creative than people think.  After the interview, Isaac and co-host Ronald Young Jr. talk more about fact-checking in fiction. They also discuss the strengths and weaknesses of first-person present tense in fiction.  In the exclusive Slate Plus segment, Julia talks about the difference between writing novels and writing for TV.    Send your questions about creativity and any other feedback to working@slate.com or give us a call at (304) 933-9675.
