I've read the majority of Heinlein's work over the past 10 years (in fact, "Revolt in 2100" was my first sci-fi book), and "I Will Fear No Evil" is the worst. It is here that Heinlein sets the tone he followed for all his later books: two one-dimensional characters -- the gruff, wise man who's always right, and the self-obsessed woman who always needs protection from her man -- lots of meaningless sex, and some claptrap about how great life was in the 1920's (when Heinlein came of age).Heinlein's early work (1930's through 1960's) is superb, and I recommend it all as some of the most creative, original writing around. But please, if you want to begin Heinlein, don't start with "I Will Fear No Evil." And if you are a devoted Heinlein fan (as I am) and want to stay that way, skip this book.
