Sarah Sentilles’ upcoming brown bag lunch chat at Eagle Harbor Book Company promises to be a fascinating discussion of art, war, violence, peace and survival.

Sentilles, author of “Draw Your Weapons,” will visit the used boon annex at 12:30 p.m. Wednesday, Aug. 9. The shop provides chips and drinks, guests are encouraged to bring their own sandwiches or salads.

RSVP by “purchasing” a free ticket at www.eagleharborbooks.com to ensure sufficient chairs/refreshments are available.

In “Draw Your Weapons,” Sentilles tells the true stories of Howard, a conscientious objector during World War II, and Miles, a former prison guard at Abu Ghraib, and in the process she challenges conventional thinking about how war is waged, witnessed and resisted. The pacifist and the soldier both create art in response to war: Howard builds a violin; Miles paints portraits of detainees.

With echoes of Susan Sontag and Maggie Nelson, Sentilles investigates images of violence from the era of slavery to the drone age. In doing so, she wrestles with some of our most profound questions: What does it take to inspire compassion? What impact can one person have? How should we respond to violence when it feels like it can’t be stopped?

“Draw Your Weapons” stirs and confronts, disturbs and illuminates.

A single book might not change the world, but this lucid, radiant and utterly original meditation on art and war might transform the way you see the world.

Sentilles is the author of “Breaking Up with God,” “A Church of Her Own” and “Taught by America.” A graduate of Yale University and Harvard Divinity School, she lives in Idaho’s Wood River Valley.
