Echoes of the Hunt - the justice chronicles, #1

Detective Lana Hayes is haunted by the death of her partner during a pursuit of a notorious serial killer who leaves cryptic clues at every crime scene. Years later, new murders arise, mirroring the same sinister pattern. Forced to confront her past, Lana teams up with Sam Carter, the reclusive former lead investigator on the original case. As they dive deeper into the mystery, old wounds are reopened, and tensions rise. Unbeknownst to Lana, Sam is hiding a dark secret-he is the mastermind behind the killings, manipulating both the investigation and her emotions.
As the body count rises, Lana's trust in Sam begins to erode, and she soon uncovers the chilling truth. In a climactic showdown, Sam is captured alive, but the justice system offers him a light sentence: fifteen years in prison. Despite his imprisonment, Lana senses that their battle is far from over. The case may be closed, but the threat of Sam's return looms large, leaving Lana with the uneasy feeling that this is only the beginning.
