When 25-year-old Jo climbed down the ramp of the freighter Canadian Star to set foot in Vancouver, BC, in the summer of 1967, she'd never heard of log salvaging. But within two-and-a-half years, the immigrant from England would quit her teaching job and join forces with one of the most enigmatic salvagers of the Sunshine Coast. Dick and Jo Hammond spent a life together chasing logs, rescuing boaters in distress, and raising their two children in BC's log salvaging mecca, Howe Sound. Combining Dick's guidance and her stubborn nature to master all challenges, Jo learned to maneuver their salvage boat, drive dogs and tie knots, sing arias to the sea lions and suckle her child while chasing rogue logs.

Edge of the Sound is both a love story and a tale of adventure between a man with an uncommonly high IQ who found his niche behind the wheel of a salvaging boat and a young woman searching for her own place in the world. Their bond was the risk of the wild and unpredictable sea, classical music, the beauty of the natural west coast and the rise and fall of tides that help and hinder their hunt for logs that have escaped between forest and mill. As they work against the forces of nature, Jo Hammond learns to change and she learns to "expect the unexpected."
