If you were asked to name the most famous Canadian authors, who would come to mind? Margaret Attwood, surely. Alice Munro, Leonard Cohen. Mordecai Richler, L. M. Montgomery, Robertson Davies, . . . and probably a handful of others if you were given a moment to think about it. And yet, even if you were given a good hour to concentrate – to name every author you could – I suspect that there would be one name invariably missing from that list: Mazo de la Roche.
