“One Good Thing,” a first novel by Patrick McGowan, a former commissioner of the Maine Department of Conservation, is described as “weaving the spirit of adventure and social justice into a 21st-century Robin Hood story—with a twist. Our avengers take to the skies over the wilds of northern Maine and remote Canada risking everything in a mad-capped scheme to kidnap a couple of crooked, greedy billionaires.”

Sherman’s Bookstores of Maine will host book signings with McGowan on Saturday, August 25, at 1 p.m. at its Boothbay Harbor store, and on Saturday, September 22, at 1 p.m. at its store in Camden.

“During the winter of 2014-15 we lost power over the entire Christmas holiday. Luckily I had this story in my head for a book. I started writing,” says McGowan. “It’s an adventure story with purpose.”

McGowan, who was born in Bangor and raised in Somerset County, has served as a legislator, a presidential appointee and as commissioner of the Department of Conservation, and has owned and operated many small businesses. His adventures have included 10 years as a skydiver and 40 years as a floatplane and backcountry airplane pilot.

“One Good Thing” is published by Polar Bear & Company, of Maine, an imprint of the non-profit Solon Center for Research and Publishing — head office is in Solon, with a showroom at 20 Main Street in Rockland. The book is available online, at local bookstores by request, or directly from the publisher.
