Oh, the '80s! I read Tempest in Eden by Sandra Brown. This is another of her early romance novels, written under the name Rachel Ryan.
In this novel, we don't have Tarzan and Jane. This time Brown paired a minister with a nude model. Of course they met when their parents (both widowed) got married. Let's take improbability and pile more on top, shall we?
Honestly, I had a hard time with this one. I just couldn't get past how dated and unlikely this story was. I definitely prefer her recent novels to her early work.
