The author of the stunning New York Times bestseller The Widow returns with a brand-new novel of twisting psychological suspense.

Her heartbroken parents were left devastated by the loss. But there is more to the story, and Kate is drawn--house by house--into the pasts of the people who once lived in this neighborhood that has given up its greatest mystery. And she soon finds herself the keeper of unexpected secrets that erupt in the lives of three women--and torn between what she can and cannot tell...
