Jack McEvoy is at the end of the line as a crime reporter. Forced to take a buy-out from the LA Times as the newspaper grapples with dwindling readership and revenues, he's got 30 days left on the job. His last assignment? Training his replacement, a low-cost reporter just out of J-school who couldn't find the police station if it was right next door to the Times, which it is.

Former FBI agent Rachel Walling is working a dead-end stint in South Dakota when she gets the call she's been dreading for four years. The Poet is back. And he has not forgotten Rachel. He has a special present for her. Harry Bosch is adjusting to life in Las Vegas as a private investigator and as a new father. He gets a call, too, from the widow of a friend who died recently. Previously in his FBI career, the friend worked on the famous case tracking the killer known as The Poet.

Harry is back, assigned to the LAPD's Open-Unsolved Unit with his former cop ally and partner, Kizmin Rider. These detectives are the Closers. They are thrown into a politically sensitive and dangerous case when a white supremacist is connected to the 1988 murder of a mixed-race girl. The police department has changed, but one thing hasn't--Harry's nemesis, Irving. The former deputy chief has been pushed from power and given a virtually meaningless new role. Full of vengeance, Irving calls Harry a "retread".

When he left the LAPD, Bosch took a file with him: the case of a production assistant murdered four years earlier during a film-set robbery. The LAPD thinks the stolen money was used to finance a terrorist training camp. Thoughts of the original murder victim were lost in the federal zeal, and when Bosch decides to reinvestigate, he quickly falls foul of both his old colleagues and the FBI. When the investigation enables him to meet up with an old friend, shadows from his past come back to haunt him.

In 1993 Harry Bosch was assigned the case of a missing person, Marie Gesto. The young woman was never found - dead or alive - and the case has haunted Bosch ever since. Thirteen years later Bosch is in the Open Unsolved Unit when he gets a call from the DA's office. A man accused of two killings is willing to confess to several other murders in a deal to avoid the death penalty. One of his victims, he says, is Marie Gesto.

Terry McCaleb's enforced quiet lifestyle on the island of Catalina is a far cry from the hectic excitement of his former role as an FBI profiler. However when small-time criminal Edward Gunn is found dead, McCaleb becomes embroiled in a disturbing and complex case leading him to cross the path of Harry Bosch. This infamous detective has always teetered on the brink of darkness in order to get inside the head of the killer. Is it possible he has stepped across that finely drawn line and embraced darkness?

When Graciella Rivers steps onto his boat, ex-FBI agent Terrell McCaleb has no idea he's about to come out of retirement. He's recuperating from a heart transplant and avoiding anything stressful. But when Graciella tells him the way her sister, Gloria, was murdered, Terry realizes he has no choice. Now the man with the new heart vows to take down a predator without a soul. For Gloria's killer shatters every rule that McCaleb ever learned in his years with the Bureau-as McCaleb gets no more second chances at life...and just one shot at the truth.

When a physicist is murdered in LA it seems the killer has no fear of publicity, leaving the body on The Mulholland overlook, a site with a stunning view over the city. And when it's discovered that the victim turned over a quantity of a lethal chemical to his killer before he died, Harry knows he has more than just a single death to worry about. Alongside the forces of Homeland Security, Harry realises he must solve the murder or face unimaginable consequences.

The shooting of a Chinese liquor store owner in LA brings Harry Bosch back to the Rodney King riots and the moment a stranger gave a young cop sanctuary. Now the debt must be repaid, and Harry soon discovers the old man's death was no ordinary holdup.

When down-at-heel lawyer Mickey Haller gets the news that his old colleague Jerry Vincent has died, he also gets an unexpected windfall. Jerry had left instructions that Mickey should inherit all of his clients - putting Mickey's stalled career back on track at a stroke. Not only that, but Vincent was about to go to bat for Walter Elliot, the Hollywood mogul accused of brutally slaying his wife and her lover, in a trial that promises big fees and an even bigger place in the media spotlight.

Mickey Haller gets the text, "Call me ASAP - 187," and the California penal code for murder immediately gets his attention. Murder cases have the highest stakes and the biggest paydays, and they always mean Haller has to be at the top of his game. When Mickey learns that the victim was his own former client, a prostitute he thought he had rescued and put on the straight and narrow path, he knows he is on the hook for this one. He soon finds out that she was back in LA and back in the life. Far from saving her, Mickey may have been the one who put her in danger.

In tough times, crime is one of the few things that still pay, but if defence attorney Mickey Haller was expecting an uptick in business during the economic downturn, the reality is a different story. Even people needing legal representation to keep them out of jail have to make cut-backs, it seems.

When Mickey Haller is invited by the Los Angeles County District Attorney to prosecute a case for him, he knows something strange is going on. Mickey's a defense lawyer, one of the best in the business, and to switch sides like this would be akin to asking a fox to guard the hen-house. But the high-profile case of Jason Jessup, a convicted child-killer who spent almost 25 years on death row before DNA evidence freed him, is an intriguing one.

When the bones of a boy are found scattered in the Hollywood Hills, Harry Bosch is drawn into a case that brings up dark memories from his past. Unearthing hidden stories, he finds the child's identity and reconstructs his fractured life, determined that he won't be forgotten. At the same time, a new love affair with a female cop begins to blossom - until a stunningly blown mission leaves him in more trouble than ever before.

Harry Bosch is facing the end of the line. He's been put on the DROP - Deferred Retirement Option Plan - and given three years before his retirement is enforced. Seeing the end of the mission coming, he's anxious for cases. He doesn't have to wait long. First a cold case gets a DNA hit for a rape and murder which points the finger at a 29-year-old convicted rapist who was only eight at the time of the murder.
