The Stepford Wives - Ira Levin

The women of Stepford are not all that they seem...All the beautiful people live in idyllic Stepford, Connecticut, an affluent, suburban Eden populated with successful, satisfied hubbies and beautiful, dutiful wives. For Joanna Eberhart, newly arrived with her husband and two children, it all seems too good to be true - from the sweet Welcome Wagon lady to all those cheerful, friendly faces in the supermarket checkout lines. But just beneath the town's flawless surface, something is sordid and wrong - something abominable with roots in the local Men's Association.

And it may already be too late for Joanna to save herself from being devoured by Stepford's hideous perfection.
