Jeff Gundy, a professor of English at Bluffton University, talks about his newly published book, “Songs from an Empty Cage: Poetry, Mystery, Anabaptism, and Peace,” during an author program Nov. 21 in Bluffton’s Musselman Library.

A poetic exploration of theology, “Songs from an Empty Cage” is a sequel to Gundy’s “Walker in the Fog: On Mennonite Writing” and also the 10th book in the C. Henry Smith Book Series. Gundy has published five books of poems and three of prose; his latest book of poems, “Somewhere Near Defiance,” is forthcoming from Anhinga Press.
