Un ancien marin quinocéen raconte ce qu'était l'existence sur la côte et sur mer au début du siècle. Il fait revivre devant nous les coutumes bretonnes, sur la frontière entre le pays bretonnant et le pays non bretonnant, ou Pays Gallo, auquel sa famille appartenait. Il nous montre aussi, dans leur vie quotidienne, les rudes marins terre-neuvas, sur leurs goélettes aux voiles déployées ou dans leurs doris perdus dans la brume. Un livre plein de sel et d'embruns. Un livre vrai, d'un homme simple.
