These Toxic Things by Rachel Howzell Hal (September 1). Mickie Lambert creates “digital scrapbooks” for clients, ensuring that precious souvenirs aren’t forgotten or lost. When her latest client, Nadia Denham, a curio shop owner, dies from an apparent suicide, Mickie honors the old woman’s last wish and begins curating her peculiar objets d’art. A music box, a hair clip, a key chain―twelve mementos in all that must have meant so much to Nadia, who collected them on her flea market scavenges across the country.

But these tokens mean a lot to someone else, too. Mickie has been receiving threatening messages to leave Nadia’s past alone.

It’s becoming a mystery Mickie is driven to solve. Who once owned these odd treasures? How did Nadia really come to possess them? Discovering the truth means crossing paths with a long-dormant serial killer and navigating the secrets of a sinister past. One that might, Mickie fears, be inescapably entwined with her own.

Constance by Matthew FitzSimmons (September 1). In the near future, advances in medicine and quantum computing make human cloning a reality. For the wealthy, cheating death is the ultimate luxury. To anticloning militants, it’s an abomination against nature. For young Constance “Con” D’Arcy, who was gifted her own clone by her late aunt, it’s terrifying.

After a routine monthly upload of her consciousness―stored for that inevitable transition―something goes wrong. When Con wakes up in the clinic, it’s eighteen months later. Her recent memories are missing. Her original, she’s told, is dead. If that’s true, what does that make her?

The secrets of Con’s disorienting new life are buried deep. So are those of how and why she died. To uncover the truth, Con is retracing the last days she can recall, crossing paths with a detective who’s just as curious. On the run, she needs someone she can trust. Because only one thing has become clear: Con is being marked for murder―all over again.

Her friends think she can work off her aggressions pounding clay in a beginners’ pottery class. But someone has mistaken Cat’s pot for a blunt instrument and they’re firing something besides clay in the art center kiln.

Now that things are really heating up, Cat’s murder investigation leads to a legendary lost collection of vases once owned by an equally legendary madam from Cincinnati’s bygone red-light district. Can Cat catch a killer before the past goes up in flames?

Jaya “Longshot” Long is the phenom of the Lame Deer Lady Stars High School basketball team and is following in the steps of her older sister, who disappeared a year previously, a victim of the scourge of missing Native Woman in Indian Country. Lolo hopes that having Longmire involved might draw some public attention to the girl’s plight, but with this maneuver she also inadvertently places the good sheriff in a one-on-one with the deadliest adversary he has ever faced in both this world and the next.

The Burning by Jonathan Kellerman; Jesse Kellerman (September 21). A raging wildfire. A massive blackout. A wealthy man shot to death in his palatial hilltop home. For Clay Edison, it’s all in a day’s work. As a deputy coroner, caring for the dead, he speaks for those who cannot speak for themselves. He prides himself on an unflinching commitment to the truth.

The race is on for Clay to find him before anyone else can. Confronted with Luke’s legacy of violence, Clay is forced to reckon with his own suspicions, resentments, and loyalties. Is his brother a killer? Or could he be the victim in all of this, too? This is Jonathan and Jesse Kellerman at their most affecting and page-turning—a harrowing collision of family, revenge, and murder.

The Missing Hours by Julia Dahl (September 14). From a distance, Claudia Castro has it all: a famous family, a trust fund, thousands of Instagram followers, and a spot in NYU’s freshman class. But look closer, and things are messier: her parents are separating, she’s just been humiliated by a sleazy documentary, and her sister is about to have a baby with a man she barely knows.

Claudia starts the school year resolved to find a path toward something positive, maybe even meaningful – and then one drunken night everything changes. Reeling, her memory hazy, Claudia cuts herself off from her family, seeking solace in a new friendship. But when the rest of school comes back from spring break, Claudia is missing. Suddenly, the whole city is trying to piece together the hours of that terrible night.

Harlem Shuffle by Colson Whitehead (September 14). “Ray Carney was only slightly bent when it came to being crooked…” To his customers and neighbors on 125th street, Carney is an upstanding salesman of reasonably priced furniture, making a decent life for himself and his family. He and his wife Elizabeth are expecting their second child, and if her parents on Striver’s Row don’t approve of him or their cramped apartment across from the subway tracks, it’s still home.

Few people know he descends from a line of uptown hoods and crooks, and that his façade of normalcy has more than a few cracks in it. Cracks that are getting bigger all the time.

Cash is tight, especially with all those installment-plan sofas, so if his cousin Freddie occasionally drops off the odd ring or necklace, Ray doesn’t ask where it comes from. He knows a discreet jeweler downtown who doesn’t ask questions, either.

Then Freddie falls in with a crew who plan to rob the Hotel Theresa—the “Waldorf of Harlem”—and volunteers Ray’s services as the fence. The heist doesn’t go as planned; they rarely do. Now Ray has a new clientele, one made up of shady cops, vicious local gangsters, two-bit pornographers, and other assorted Harlem lowlifes.

Thus begins the internal tussle between Ray the striver and Ray the crook. As Ray navigates this double life, he begins to see who actually pulls the strings in Harlem. Can Ray avoid getting killed, save his cousin, and grab his share of the big score, all while maintaining his reputation as the go-to source for all your quality home furniture needs?

Harlem Shuffle’s ingenious story plays out in a beautifully recreated New York City of the early 1960s. It’s a family saga masquerading as a crime novel, a hilarious morality play, a social novel about race and power, and ultimately a love letter to Harlem. But mostly, it’s a joy to read, another dazzling novel from the Pulitzer Prize and National Book Award-winning Colson Whitehead.

Stalker Stalked by Lee Matthew Goldberg (September 17). Lexi Mazur is a depressed, alcoholic, pill-popper whose only joy has become her reality TV shows, often fantasizing that the people on TV are a part of her world. After her boyfriend Steve leaves her, she fixates on the show Socialites and its star Magnolia Artois, following every facet of the girl’s life on social media in the hopes of befriending and becoming more like her.

But stalking isn’t new to Lexi. She ultimately won over her ex Steve by following and manipulating every minute detail about him so he’d fall for her. In fact, she landed her other ex-boyfriend Jeremy in the same way. Being a pharma rep, she’s used to manipulation to get doctors to buy her drugs, along with the perk of saving pills for herself.

But what happens when the stalker gets stalked?

Recently, Lexi has felt someone watching her: in her apartment in Queens, at her job. At first, she thinks her mind’s playing tricks, but the watcher is behaving just like she would. And soon they begin leaving threatening clues like she starts to do to Magnolia once her obsession grows more dangerous. Is it one of her exes out for revenge? Her only real friend from childhood who she’s always had an unhealthy rivalry? A detective who may have figured her out? The reality star Magnolia trying to turn the tables? Or even someone she might not know?

Lexi learns the only way to beat her stalker is to use her own stalking prowess to outsmart them at their own game. But has she finally met her match?

Horseman (A Tale of Sleepy Hollow) by Christina Henry (September 28). Everyone in Sleepy Hollow knows about the Horseman, but no one really believes in him.

More than thirty years after those storied events, the village is a quiet place. Fourteen-year-old Ben loves to play “Sleepy Hollow boys,” reenacting the events Brom once lived through. But then Ben and a friend stumble across the headless body of a child in the woods near the village, and the discovery makes Ben question everything the adults in Sleepy Hollow have ever said. Could the Horseman be real after all? Or does something even more sinister stalk the woods?

But they are out of luck.

An unexpected visitor—an old pal of Elizabeth’s (or perhaps more than just a pal?)—arrives, desperate for her help. He has been accused of stealing diamonds worth millions from the wrong men and he’s seriously on the lam.

Then, as night follows day, the first body is found. But not the last. Elizabeth, Joyce, Ron and Ibrahim are up against a ruthless murderer who wouldn’t bat an eyelid at knocking off four septuagenarians. Can our four friends catch the killer before the killer catches them?  And if they find the diamonds, too?

The Body on the Bed by Leonard Krishtalka (September 28). Mary finds the body on the bed in the house next door. Smart, tough and inquisitive, she covers the murder trial as the first woman reporter for the Kansas Daily Tribune. Amid the upheaval of post-Civil War Lawrence, she unravels the diabolical plots and desperate lives that led to three dead bodies and a shocking last act.

Did a doctor’s brazen affair with his patient’s wife incite him to murder? On the morning of April 28, 1871, the body of Isaac Miles Ruthman is found poisoned in his bed in Lawrence, Kansas. His doctor, John J. Medlicott, a fervent churchgoer, is arrested and charged with first degree murder. He’s carrying a picture of Ruthman’s wife, Anne Catherine, and two of her love poems in his wallet. He’d visited Ruthman the previous evening to give him a medicinal powder–a poison cocktail of deadly nightshade and morphine, according to the autopsy.

Is it a coincidence that the doctor’s wife, Sarah, died suddenly and mysteriously just four months earlier? Did Medlicott first kill her, then Ruthman? Or did Ruthman commit suicide, depressed over his finances and ill health–authorities had to break into his bedroom when they found the door locked from the inside.

Mary Fanning, sharp, strong-willed, and the first woman correspondent for the Kansas Daily Tribune, is assigned to report on the trial and investigate Ruthman’s poisoning. Her independence leads her to fight for suffrage for women and Blacks in post-Civil War Kansas. Her ardor leads her into an illicit love affair with a woman. Her incisive mind leads her to uncover lives torn by lust, obsession, and deceit, a trail of dead victims, and the fiendish scheme behind the body on the bed.
