Nora Roberts' Angels Fall (2007)

After a devastating trauma back east, a woman relocates to a quiet Wyoming mountain town, hoping to rebuild her life in peace. But her fresh start shatters when she stumbles upon a murder deep in the woods. Now, trapped in a small community where everyone knows each other—and no one trusts an outsider—she must decide whether to stay silent or risk everything to expose the killer hiding among her new neighbors.
