Without a Trace by Stacy Claflin

How many secrets can one gated community hide?

Ariana and Damon have just started to rebuild their lives when more bones are found in their tight-knit neighborhood. These have nothing to do with the remains found earlier.
That means one thing — another killer is roaming free.
The police are investigating, but Ariana’s friend Maya has discovered startling clues that she can’t tell them. But when Ariana’s own family is in crisis, she can’t worry about what might be unraveling all around them… until the mystery proves too much to ignore and the only way to peace is to find answers.

A neighbor is lying about something. Ariana must hurry to get to the bottom of it before another life ends up on the line. And it could be hers.
