A year has passed since LAPD detective Renée Ballard quit the force in the face of misogyny, demoralization, and endless red tape. But after the chief of police himself tells her she can write her own ticket within the department, Ballard takes back her badge, leaving “the Late Show” to rebuild and lead the cold case unit at the elite Robbery-Homicide Division.

For years, Harry Bosch has been working a case that haunts him—the murder of an entire family by a psychopath who still walks free. Ballard makes Bosch an offer: come volunteer as an investigator in her new Open-Unsolved Unit, and he can pursue his “white whale” with the resources of the LAPD behind him.

First priority for Ballard is to clear the unsolved rape and murder of a sixteen-year-old girl. The decades-old case is essential to the councilman who supported re-forming the unit, and who could shutter it again—the victim was his sister. When Ballard gets a “cold hit” connecting the killing to a similar crime, proving that a serial predator has been at work in the city for years, the political pressure has never been higher. To keep momentum going, she has to pull Bosch off his own investigation, the case that is the consummation of his lifelong mission.

The two must put aside old resentments and new tensions to run to ground not one but two dangerous killers who have operated with brash impunity. In what may be his most gripping and profoundly moving book yet, Michael Connelly shows once again why he has been dubbed “one of the greatest crime writers of all time” (Ryan Steck, Crimereads).

Praise for Desert Star:

“Thrilling… Both cases require deep dives into the past; both lead to great action scenes; and, as always, Connelly displays his encyclopedic knowledge of the latest forensics… Ranks up there with Connelly’s best.”―Publishers Weekly

“Readers will be glad to know that Connelly is still bringing the same intensity and atmosphere to his iconic series.”―Crimereads

Praise for The Dark Hours:

“One of this month’s best thrillers… Ballard and Bosch are a great combination as they work in and around a police force that Ballard believes too often aims to ‘protect and serve the image instead of the citizens.’”―Richard Lipez, Washington Post

“A thoroughly engrossing procedural… The Dark Hours offers plenty of shocking scenes and clever surprises."―Tom Nolan, Wall Street Journal

“Outstanding… Connelly is the most consistently superior living crime fiction author. The Dark Hours just reinforces that.”―Oline H. Cogdill, South Florida Sun Sentinel

“Extraordinary… [Connelly] is one of the best in the business at writing about investigations and creating intense suspense, but the relationship between Ballard and Bosch—a professional friendship that grows out of two brilliant minds dedicated to the same difficult but important work—is the cherry on top.”―Collette Bancroft, Tampa Bay Times

Desert Star by Michael Connelly is a somber, gripping crime novel that brings together Renée Ballard and retired detective Harry Bosch as they dive into cold cases that still haunt Los Angeles and themselves. The book opens with Ballard, now back at the LAPD and running the Open-Unsolved Unit—essentially the cold case division—after leaving the force in frustration in a previous story. She’s been given this job partly because it keeps her away from the spotlight and partly because no one else wants the enormous, emotionally heavy workload of unsolved murders. Ballard sees it differently: she views these forgotten victims and their families as her responsibility, and she wants the unit to matter again. Her idea is to use modern tools—especially advances in DNA—to breathe new life into old files that were set aside when leads dried up. To do that, she needs help from someone who lives and breathes unsolved cases: Harry Bosch.

Bosch, older now and officially retired, still carries the weight of past victims on his shoulders. One case has never let him go—the murder of an entire family in a house on a hill, the Gallagher family, whose bodies were found years ago. Bosch spent a long time chasing that killer and never got his man. That failure stays with him as a personal shame. When Ballard invites him to unofficially join her unit as a volunteer, she offers him something priceless: a chance to finally work that cold case again. Bosch mostly wants the Gallagher file, but Ballard makes it clear that if he wants to dig into that, he also has to help on the rest of the unit’s workload. Their arrangement becomes a mix of formal LAPD procedure and Bosch’s stubborn, independent instincts, creating a tense but dynamic partnership.

Alongside the Gallagher case, Ballard has her own unresolved ghost: the murder of a teenage girl named Daisy Clayton, a victim found dead long ago with her body discarded like trash. Bosch has already tried to solve Daisy’s case in an earlier book, getting close but not finishing it. Now, under Ballard’s leadership, Daisy’s file becomes a priority again. The novel balances these two major investigations—the Gallagher family massacre and Daisy’s death—while also touching other cold cases that cross their desks. Each file is a story of someone whose life ended violently and whose name was buried in paperwork, and Connelly uses that structure to show both the relentless grind of detective work and the emotional toll of chasing long-dead leads.

Ballard and Bosch’s working relationship is one of the most interesting parts of the book. Ballard is used to fighting her own battles against department politics, sexism, and indifference. She pushes hard, sometimes bending rules, but she still has to answer to bosses and keep the unit alive. Bosch, on the other hand, is free from official constraints in one sense—he’s retired—but he’s limited by age, health, and the fact that he technically shouldn’t even be working these cases. He’s driven by pure obligation to the victims rather than to the LAPD. Ballard respects him but also resents his tendency to go off on his own. She’s focused on the bigger picture: making the unit effective, protecting it from being shut down, and making sure their work holds up in court. Their disagreements feel genuine and human. They argue over tactics, over how far to go, and over whether the ends justify the means, but underneath it they share the same core: the belief that the dead deserve justice, no matter how late.

The Gallagher case, Bosch’s main obsession, pulls him deeper into dark corners of the past. The family was killed in what looked like a carefully planned, cold-blooded attack, and the evidence suggests someone with knowledge of the house and their routines. Over the years, clues have gone stale, witnesses have scattered, and memory has blurred. Bosch re-reads every file, every photo, trying to see something he missed before. Modern forensic tools become crucial: new DNA databases, better matching techniques, and the ability to re-test old samples give them a new angle. As they chase possible suspects, they uncover hints that the killer might still be out there, living an ordinary life after having murdered an entire family. That possibility gives the investigation both urgency and dread—this isn’t just a puzzle; it’s about someone who got away with something unforgivable.

Daisy Clayton’s case brings a different, more personal kind of pain. Daisy was young, vulnerable, and her murder was part of a pattern of killings of homeless and runaway women. Bosch has known Daisy’s mother and has seen the grief that never fades when a parent loses a child and never gets answers. Ballard, too, is touched by this case, not just professionally but emotionally. The question is not only who killed Daisy, but how many similar victims were missed or minimized over the years. As Ballard and Bosch dig in, they explore possible links between Daisy’s death and other cases, looking for a thread that ties them together. They find that some women were treated as disposable by society, and their murders were never truly prioritized, which makes Ballard and Bosch even more determined to fight for Daisy’s memory.

Throughout the novel, Connelly weaves in the reality of police work—the forms, the chain of evidence, the politics—without losing the emotional core. Ballard has to worry about budget, staffing, and higher-ups who would happily cut her unit if it doesn’t produce quick results that make the department look good. Cold cases, by nature, are slow, uncertain, and often messy; they don’t always end neatly. Bosch has to deal with the limitations of his own body and the constant sense that time is running out—for him and for the cases. He’s aware that he might not have many big investigations left in his life, so every failure feels heavier, and every breakthrough feels more precious.

As the investigations progress, the book builds toward key reveals in both the Gallagher and Daisy cases. It doesn’t present these discoveries as sudden flashes of genius, but as the result of persistent, painstaking work—re-checking old interviews, re-testing evidence, revisiting crime scenes, and following small clues that others ignored or dismissed. Ballard and Bosch face danger, because the people connected to these murders have reasons to keep the truth buried. There are scenes of tension and confrontation, but the deeper drama lies in the moral weight of their choices. When they finally close in on answers, those answers come with consequences, not just for suspects and families but for Bosch himself.

The title Desert Star carries symbolic meaning tied to Bosch’s psyche and the idea of something shining faintly in a vast, dark emptiness. The desert imagery hints at isolation and silence—the way cases can dry out and vanish—and the star suggests the tiny points of light that are hope, truth, and justice. Bosch’s journey in this book feels like a man tracing those faint lights, knowing he might not see all of them resolved before his own time ends. Ballard, younger and still in the system, represents another kind of star: someone who can carry the work forward, if she can keep her integrity and her unit alive.

By the end of Desert Star some questions have answers and some do not. Ballard and Bosch manage to bring long-delayed justice to victims who had nearly been forgotten, and those successes matter deeply to them and to the families involved. But the cost is real—emotional strain, professional risk, and the painful awareness that for every cold case they solve, many more remain in boxes on shelves. Bosch’s arc is especially poignant: he is not just solving crimes, he is trying to settle his own soul, to walk away from life knowing he did everything he could. Ballard, watching him, understands that his way of working—relentless, uncompromising—will shape how she chooses to do her own job in the years ahead. The novel closes on a note that is both heavy and quietly hopeful: the work is endless, the darkness is deep, but as long as someone like Ballard and Bosch keeps pushing, that desert star of justice continues to shine, however faintly, over the lives that were taken and the truths that still wait to be found.
