To answer your question, anything by Joan Hess (fiction, humorous mystery series) and Maya Angelou's "I Know Why the Caged Bird Sings". There's one called "Hot Springs" and I can't recall the title of the true story of the murder of Nancy Dillard. Lots of history about the Little Rock school integration and the West Memphis Three.
Can't stop updating. Here's the two Joan Hess series set in Arkansas. I've read them all. Joan lived in Fayetteville and the Claire Malloy series is set there. I think she used Gravette as the setting for the Maggody series. When she passed away, she left the story lines hang. The Nancy Dillard-Lyon book is "Poisoned Dreams".
