AUGUSTA — Maine author Caitlin Shetterly will read from and discuss her latest book, “Modified: GMOs and the Threat to Our Food, Our Land, Our Future,” at 6:30 p.m. Wednesday, June 21, in the Community Room at Lithgow Public Library, 45 Winthrop St.

The book is a disquieting and meditative look at the issue that started the biggest food fight of our time — GMOs. From a journalist and mother who learned that genetically modified corn was the culprit behind what was making her and her child sick, “Modified” is a must-read book for anyone trying to parse the incendiary discussion about genetically modified foods.

Shetterly is the author of “Made for You and Me: Going West,” “Going Broke, Finding Home” and the bestselling “Fault Lines: Stories of Divorce.” Her work has been featured in The New York Times Magazine, Elle and Self, and online at Oprah.com and Medium.com, as well as on “This American Life” and various other public radio shows. She lives with her family in Maine.

Books will be available for purchase and signing.
