Violet’s ability to sense dead bodies is an asset to forensic psychologist Sara Priest, who enlists her to uncover a string of murders by a man known as “the girlfriend collector.” Now the serial killer is on the lookout for a new "relationship," and Violet may have caught his eye.

For as long as Tessa can remember, her country has been at war. When Gideon, a local boy, wins an award for courage, a strange chain of events is set in motion; soon, Tessa finds herself in enemy territory and stumbles upon a shocking secret. 

Violet can sense the echoes of those who've been murdered and the matching imprint that clings to their killers. But though she works to keep her morbid ability a secret, she unwittingly draws the attention of both the FBI and someone else—someone dangerous.
