A rather sprawling novel set in the period of the French and Indian wars in Canada, 200 years ago, as the twins, red-headed Marguerite and Paul Boissart, children of a leading habitant family near Montreal, are thrust by fate -- and their temperaments -- into adventures that include Paul's experiences as a courier du bois and Marguerite's unhappy love affair, Indian massacre, capture by and escape from the Indians. Good picture of the life on the frontier, of the brief glimpses of the glamor translated from Paris to Quebec, of the primitive beginnings of social levels and taboos. Good story telling -- but the style falls down when it comes to dialogue, which seems artificial and unreal. The audience? Those who like many-textured historical and regional and period stories, with lots of action.
