Sometimes the dead can't be silenced.
Violet thought she had made peace with her unique ability to sense the echoes of the dead and the imprints that cling to their killers . . . until she acquired an imprint of her own. Forced to carry a reminder of the horrible events of her kidnapping, Violet is more determined than ever to lead a normal life. However, the people who run the special investigative team she works for have no intention of letting her go. Violet will do whatever it takes to keep her loved ones safe—even if it means lying to her boyfriend, Jay. But when an echo calls to her, she stumbles upon a murder scene unlike anything she's ever witnessed. The murders are frenzied and twisted, and the killer left a disturbing calling card for all to see—a brimstone cross sketched in blood on the wall. And Violet finds herself pulled into a deadly hunt for a vicious madman with an army of devoted followers. Violet has survived dangerous situations before, but she quickly discovers that protecting those closest to her is far more difficult than protecting herself.
