This weekend's "Sunday Square Off" highlights the work of three Arizona authors. The show features conversations with:

-Amy Silverman, managing editor of Phoenix New Times, who's written a revealing memoir, "My Heart Can't Even Believe It," about raising her daughter Sophie, who has Down syndrome.

-Jeremy Duda, a reporter with the Arizona Capitol Times, whose new book, "If This Be Treason," explores the history of dissent and treason since America's founding.

-Arizona State University Professor Kyle Longley, who tells the story of small-town Arizona during the 1960s and nine young men who went off to fight in Vietnam, in "The Morenci Marines."

"Sunday Square Off" airs at 8 a.m. Sundays on 12 News, right after "Meet the Press."
