I read the book, and enjoyed both.
I took them as distinct entities.
I really enjoyed The Moon is a Harsh Mistress, Starship Troopers, and Stranger in a Strange Land.

I have enjoyed many of Heinlein’s novels, especially the Lazarus Long series of books:

Methuselah’s Children, 1958 (originally a serialized novella in 1941)

I Will Fear No Evil, 1970

Time Enough for Love, 1973

The Cat Who Walks Through Walls, 1985

Some are silly fantasy, like

The Number of the Beast, 1980
and
Job: A Comedy of Justice, 1984, but still good reading.
