Stranger in a Strange Land

Here is why James Mustich thinks it should be one of the 1000 Books You Read Before You Die:

Robert Heinlein's most famous and influential work, albeit not his most brilliantly speculative, is surely Stranger in a Strange Land, a book whose questioning of social mores and religious certitude have made it as congenial to some readers as it has been controversial to others. Astonishingly entertaining, yet full of meaty philosophical and quotidian barbs, rife with pathos and laughs, this novel—whether in its original form or the expanded author’s cut—remains as poignant and provocative as the day it was issued.
