The Appalachian Trail --  2,184 miles of public pathway through the wilds of one of the oldest mountain ranges in the world, the Appalachians. The trail, envisioned by forester and conservationist Benton MacKaye as a refuge from life in the industrialized metropolis, was completed in 1937. In the decades following, roughly 11,000 people have completed the through hike.

In 2010, Paul Molyneaux and his son Asher joined their ranks. Asher was 8 years old, the second-youngest person to complete the trail. Paul shares their journey in his latest book, "A Child's Walk in the Wilderness: A Father and his 8 Year old Son take on the Appalachian Trail."

Paul is also the author of The Doryman's Reflection and Swimming in Circles, and writes about commercial fishing practices for The New York Times and other publications. He won a 2007 Guggenheim Fellowship to study sustainable fisheries in India, Chile, and Iceland. He lives in Maine and Mexico.

The book launches at 6 p.m. on Sat. Feb. 16 at the Interlingua Language School in Phoenix. It includes a book signing and photo presentation.
