It's readable. I remember when it was first published and it was all the rage. When I read it then, it seemed a lot deeper than it is.
People making mistakes with their eyes wide open then miserable about the results. It's not a great romance and most of it is pretty predictable with predictable results.
Once the big lust between Meggie and Ralph is consummated, the story bogs down. I had to push to make myself finish reading it. Dane and Justine just weren't interesting enough to keep the story going. Even taking them away from the isolation of the homestead didn't add enough to keep them interesting. Its like McCullough spent all her energy on the big romance and didn't have anything left or lost interest in her own story once Ralph and Meggie had their fling.
Still, it isn't all bad. I just now scratch my head and wonder what all the fuss was about at the time.
