A sequel to Once a Wilderness in that it continues the fortunes of the Mark olan, bringing them up to 1933. But in itself a robust tale of the American scene -- Michigan, both in its agricultural aspects and in the growth of a boom city, Pontiac -- a story that carries its own weight, but that should create plus sales for the earlier title. The old Captain, John Mark, is a background figure for his grandsons, especially the industrialist, Clayt Galo, and the artist, John Mark. For those who have turned from novels of the soil and prefer the industrial scene, this novel will have more appeal than the other. Personally, I am frank in saying that I think it is a less important book, lacking the vitality of Once a Wilderness. Its market is assuredly those who read the first book, for the characters and situations are skilfully evolved in the sequel. And the Marks deserve to be known for their own sake.
