The neighbor's secret / Alison L. Heller.
(Adult Book)

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. Or does it? What happened to Lena's family fifteen years ago was a tragic accident, and she will never admit otherwise. Devoted wife and mother Annie refuses to acknowledge--even to herself--the weight of a past shame. And new resident Jen wants friends, but as always, worry about her troubled son gets in the way. When late-night acts of vandalism target the women of the book club in increasingly violent and personal ways, they will be forced to decide how far to go to keep their secrets. At least they all agree on what's most important: protecting their children at any cost--even if it means someone has to die.
