Northwest of Montreal, through a valley always in sight of the low mountains of the Laurentian Shield, the Ottawa River flows out of Protestant Ontario into Catholic Quebec. It comes down broad and ale-coloured and joins the Saint Lawrence, the two streams embrace the pan of Montreal Island, the Ottawa merges and loses itself, and the main-stream moves northeastward a thousand miles to sea. With these words Hugh MacLennan begins his powerful saga of Athanase Tallard, the son of an aristo-cratic French-Canadian tradition, of Kathleen, his beautiful Irish wife, and of their son Paul, who struggles to establish a balance in himself and in the country he calls home.
