Following their last trip to Afghanistan, Olivia and Keith have both been plagued with nightmares about losing one of their military brothers. Despite having difficulty adapting to normal life, Olivia has re-established her relationship with Patricia, her long-term partner, and has become a detective within the New York police department; however, Keith becomes a teacher hoping to steer young teens on the right path, but his demons take a toll on him, and he finds the cure to his nightmares.

An ATF special unit led by Victor Hernandez, whose family he had long ignored after disapproving of his daughter’s life choices, is sent to New York to apprehend an elusive and vicious criminal, only known as “Sombra.” While trying to bring down Sombra, Victor longs for a reconciliation with his daughter Olivia.

As Olivia investigates a string of murders of known criminals, she learns Keith has secretly taken justice into his hands, and she confronts him. During the confrontation, Keith asks Olivia to help him mete out rough justice, but as a sworn officer, Olivia refuses. However, when Patricia gets attacked by one of Sombra’s men, Olivia joins Keith in a vigilante quest for Patricia’s attacker.

During the final showdown, Olivia must choose between reclaiming her family’s future or rectifying a past mistake.

Diana O’Toole is perfectly on track. She will be married by thirty, done having kids by thirty-five, and move out to the New York City suburbs, all while climbing the professional ladder in the cutthroat art auction world. She’s an associate specialist at Sotheby’s now, but her boss has hinted at a promotion if she can close a deal with a high-profile client. She’s not engaged just yet, but she knows her boyfriend, Finn, a surgical resident, is about to propose on their romantic getaway to the Galápagos—days before her thirtieth birthday. Right on time.

But then a virus that felt worlds away has appeared in the city, and on the eve of their departure, Finn breaks the news: It’s all hands on deck at the hospital. He has to stay behind. You should still go, he assures her, since it would be a shame for all of their nonrefundable trip to go to waste. And so, reluctantly, she goes.

Almost immediately, Diana’s dream vacation goes awry. Her luggage is lost, the Wi-Fi is nearly nonexistent, and the hotel they’d booked is shut down due to the pandemic. In fact, the whole island is now under quarantine, and she is stranded until the borders reopen. Completely isolated, she must venture beyond her comfort zone. Slowly, she carves out a connection with a local family when a teenager with a secret opens up to Diana, despite her father’s suspicion of outsiders.

In the Galápagos Islands, where Darwin’s theory of evolution by natural selection was formed, Diana finds herself examining her relationships, her choices, and herself—and wondering if when she goes home, she too will have evolved into someone completely different.

Lauren Abrams wants nothing to do with her damaged mother, whose spurious testimony sent Lauren’s father to prison for murder years ago. After a serial killer’s confession to the crime restored justice, Lauren chose to live with her father and grandmother. Now an adult, Lauren has come home to the Sacramento family estate for good, her mother’s lies be damned…

It’s been decades since Donna made her cheating boyfriend pay, but she hasn’t forgotten the past. She knows her estranged daughter has made a terrible mistake by returning to the estate. There’s more to the story of the welcoming old homestead―and her childhood―than Lauren knows.

As Lauren settles in, she is haunted by the questions of what really happened with her father, what her mother might be hiding, and what secrets the family ranch holds. It’s getting so dark, Lauren may not be able to see the truth to save her life.

Forensic pathologist Kay Scarpetta has come almost full circle, returning to Virginia as the chief medical examiner, the state where she launched her storied career. Finding herself the new girl in town once again after being away for many years, she’s inherited not only an overbearing secretary, but also a legacy of neglect and potential corruption.

She and her husband Benton Wesley, now a forensic psychologist with the U.S. Secret Service, have relocated to Old Town Alexandria where she’s headquartered five miles from the Pentagon in a post-pandemic world that’s been torn by civil and political unrest. Just weeks on the job, she’s called to a scene by railroad tracks where a woman’s body has been shockingly displayed, her throat cut down to the spine, and as Scarpetta begins to follow the trail, it leads unnervingly close to her own historic neighborhood.

At the same time, a catastrophe occurs in a top-secret laboratory in outer space, endangering at least two scientists aboard. Appointed to the highly classified Doomsday Commission that specializes in sensitive national security cases, Scarpetta is summoned to the White House and tasked with finding out exactly what happened. But even as she works the first potential crime scene in space remotely, an apparent serial killer strikes again very close to home.
