Cloned Lives

For my tastes, there was way too much time spent on the characters.
The book was written in the mid 1970s, much of it takes place in 2020 +- 20 years.

The science fictional elements were interesting, automated highways, colonies on the moon, colony ships and the beginnings of Star Trek replicators.

But you could have made the 5 main characters quintuplets, not clones and the story would have been the same.

I did like the writing style so I will try some of her other books.
