Is The Help a One Book Wonder?

This was a book group read that we had to really scramble to get enough copies of because of the popularity of it.  It is her first (and only so far) book, but what a doozieSet in Jackson, Mississippi in the early 1960s around the time of Medgar Evers’ assassination, it alternates among three voices: Skeeter, a young white woman raised on a comfortable farm outside Jackson mostly by her family’s maid, Constantine; Aibileen, an older (maybe late 50s?) African-American maid working for an empty-headed white woman–a close friend pf Skeeter’s–whose idea of having children is to see them as little as possible; and Minny, a somewhat younger African-American maid whose inability to be sufficiently subservient constantly causes her to lose jobs as a maid.  Aibileen’s and Minny’s chapters are rendered in their dialect (e.g., “I’m on go there” instead of “I’m going to go there”), as Skeeter’s are rendered in hers, but as a college-educated white woman, Skeeter writes more or less standard English.

I liked all three characters. Some of the other characters in the book, such as Skeeter’s friend and Aibileen’s employer Elizabeth and the book’s villain Hilly Holbrook, another friend of theirs and president of the women’s League in Jackson, are portrayed as pure bigots. Can people really have been so cruel?
     Skeeter, an aspiring journalist, persuades Aibileen, and eventually Minny, to share with her their true feelings about their white employers.  In so doing, Skeeter is transformed from a kind person who does not question the rules of the society in which she was raised to one who really “gets it” and becomes willing to break those rules.  But at the end, Skeeter, like the author, leaves the South entirely, while Aibileen, Minny, and the other maids in the novel have to remain behind and deal with living in a racially bigoted society.
In the end I did love this book and have recommended it to several people. You can check out the HELP web page if your group is reading it. 

And now the question is "Is the author a one book wonder?"
