Neighborhood Watch by Sarah Reida

A killer terrorizes the morally bankrupt residents of an upscale neighborhood, leading them to turn to-and on-one another to survive.
The neighborhood of Oleander Court is the poster child for suburban bliss. The residents compare lawns beautified by hired help. They monitor home values. They toss perfect furniture because they wanted tapioca, not beige.
But when a string of murders rips through the neighborhood, suspicions abound as new secrets come to light. And as more and more bodies are taken away, it becomes clear that the killer is strategically selecting each and every victim, picking off the shallowest, most wasteful of the lot in spectacular fashion and leaving everyone in the neighborhood to wonder: Who's next?
While most of their neighbors scatter like well-dressed cockroaches, a small group of the neighborhood ladies team up to solve their local mystery and restore their once-peaceful lives. But is this ragtag collection of amateur sleuths truly a united front? With reputations, freedom, and personal sanity on the line, the ladies must unmask the killer . . . even if the killer is among them.
