How well do you really know your neighbors? With its sprawling yards and excellent schools, Cottonwood Estates is the perfect place to raise children. The Cottonwood Book Club serves as the subdivision’s eyes and ears, meeting once a month for discussion, gossip, and cocktails. If their selections trend toward twisty thrillers and salacious murder mysteries, it’s only because the members feel secure that such evil has no place in their own cul-de-sacs.
