San Diego private investigator Rick Cahill’s wife, Leah, has fled with their daughter, Krista, to her parents’ home in Santa Barbara. She fears Rick’s violent outbursts brought on by his potentially fatal brain disorder, CTE. Rick desperately wants to reunite his family and help provide for Krista’s future --- one he fears he won’t be alive to see. A jumpstart toward that future appears in the form of Peter Stone, Rick’s longtime enemy. Stone offers Rick $50,000 to find a woman he claims can save his life with a kidney transplant. Rick can’t pass up the chance to buttress Krista’s future. When what seems like a simple missing person case spirals out of control into cryptocurrency machinations, dead bodies and an outgunned faceoff, Rick is forced to battle evil from his past.

Private investigator Rick Cahill has been running from his past and chasing the truth his whole life. But his past is relentless --- and so is his CTE, a disease caused by repeated head traumas that has attacked his body and his mind. As Rick struggles to keep his family together, he does a favor for Sara Bhandari, a business contact. Then Sara is murdered, and the police believe her to be yet another victim of a serial rapist who has been terrorizing greater San Diego. But Rick has reason to question their theory. Determined to find the truth at any cost, and against his wife’s warnings, he investigates on his own. Along the way, he bumps up against a sinister private investigative agency and a shady shell corporation that may be hiding more than company secrets.

Rick Cahill's fiancée, Leah Landingham, is pregnant with their first child, and Rick is doing PI work that pays well and keeps him out of danger. Then a doctor gives him the bad news about the headaches he’s been suffering --- CTE, which leads to senility and early death --- a secret he keeps from Leah and his best friend, Moira MacFarlane. When Moira asks him to monitor her son, Luke --- who’s broken a restraining order to stay away from his girlfriend --- a simple surveillance explodes into greed, deceit and murder. Luke goes missing, and Rick’s dogged determination compels him to follow clues that lead to the exploration of high finance and DNA cancer research. Ultimately, Rick is forced to battle sadistic killers as he tries to find Luke and stay alive long enough to see the birth of his child.

Blinded by a gunshot wound to the face while working as a private investigator nine months ago, Rick Cahill is now sure of only one thing: he has to start a new life and leave his old one behind. He’s still trying to figure out what that life is when his onetime partner, Moira MacFarlane, asks for his help on a case she’s taken for his former best friend. The case is simple and Moira only needs him for one interview, but Rick is wary of waking sleeping demons. Ultimately, he goes against his gut and takes the case, which quickly turns deadly. Rick’s old compulsion of finding the truth no matter the cost --- the same compulsion that cost him his eyesight and almost his life --- battles against his desire to escape his past. The stakes are raised when his friend is implicated in murder and needs his help.

Krista Landingham, Rick Cahill's former partner on the Santa Barbara Police Department, is dead. When Rick goes to the funeral in the city where his wife was murdered and where he is seen as guilty for her death in the eyes of the police, he discovers that Krista’s death may not have been a tragic accident, but murder. Hired by Krista’s sister, Leah, to investigate, Rick follows clues that lead him to the truth --- not only about Krista’s death, but about the tragedy that ruined his life. Along the way, Leah shows him that his life can be salvaged and he can feel love again if he can just move beyond his past. The past is Rick’s present and will always be until he rights his one great wrong. In the end, Rick is left with a decision that forces him to confront the horrific actions he’ll need to take to exact revenge and achieve redemption.

But as he grapples with his father's past, the woman he still loves pleads with him to find out if her husband is having an affair --- or is involved in something much more sinister.

He may never get the chance to find out, as killers who will do anything to protect their secrets lurk in the shadows.

La Jolla Chief of Police Tony Moretti is convinced that Private Investigator Rick Cahill killed a missing person. With Moretti on his tail and the bank about to foreclose on his house, Rick takes a paying case that will stave off the bank, but pits him against Moretti and the La Jolla Police Department.
