We interviewed Mark Zimmermann, author of Pebblebrook Press's forthcoming poetry collection Impersonations, to find out more about his writing process and his experiences with the literary form of the lipogram. Zimmermann is a Wisconsin native currently living in Milwaukee. He was featured in Pebblebrook's first release, the anthology Masquerades and Misdemeanors, and he has spent time teaching humanities and writing courses, both abroad and here in the United States. Impersonations is his first collection.
