“Let no one ignorant of geometry enter here,” Plato warned would-be philosophers. Mathematician Karl Sigmund agrees. In THE WALTZ OF REASON, he shows how mathematics and philosophy together have shaped our understanding of space, chance, logic, cooperation, voting and the social contract. Sigmund shows how game theory is integral to moral philosophy, how statistics shaped the meaning of reason, and how the search for a logical basis for math leads to deep questions about the nature of truth itself. But this is no dry tome: Sigmund’s wit and humor shine as brightly as his erudition.

Black Joy is everywhere. From the bustling streets of Lagos to hip-hop blasting through apartment windows in the Bronx. From the wide-open coastal desert of Namibia to the lush slopes of Jamaica’s Blue Mountains. From the thriving tradition of Candomblé in Bahia to the innovative and trendsetting styles of Soweto, and beyond, Black Joy is present in every place that Black people exist. Now, at last, is a one-of-a-kind celebration of this truth and a life-giving testament to one of the most essential forces that fuels Black life. International in the scale, fist-raising in the prose, and full of gorgeous works by dozens of acclaimed artists, THE BLACK JOY PROJECT does what no other book has ever done. In words and art, it puts joy on the same track as protest and resistance...because that is how life is actually lived.

Fifteen-year-old Ámbar has never known any parent other than her father, Víctor Mondragón, nor any life other than his. On any given Friday night, Ámbar longs to be at the arcade or a rock concert, but she’s more likely to be patching up Víctor’s latest bullet hole in a dingy motel or creating a new set of fake identities for the both of them. When a tattooed mercenary kills Víctor’s best friend and vows that Víctor is next, father and daughter set off on a joyride across Argentina in search of bloody retribution. But Ámbar’s growing pains hurt worse than her beloved sawed-off shotgun’s kickback as she begins to question the structure of her world. How much is her father not telling her? Could her life ever be different? And will she survive long enough to find out?

Nealon returns from prison to his house in the West of Ireland to find it empty. No heat or light, no sign of his wife or child. It is as if the world has forgotten or erased him. Then he starts getting calls from a man who claims to know what's happened to his family --- a man who will tell Nealon all he needs to know in return for a single meeting. In a hotel lobby, in the shadow of an unfolding terrorist attack, Nealon and the man embark on a conversation shot through with secrets and evasions, a verbal game of cat and mouse that leaps from Nealon's past and childhood to the motives driving a series of international crimes launched against "a world so wretched it can only be redeemed by an act of revenge."

Ten years ago, Theodora “Teddy” Angstrom’s older sister, Angie, went missing. Her case remains unsolved. Now Teddy’s father, Mark, has killed himself. Unbeknownst to Mark’s family, he had been active in a Reddit community fixated on Angie, and Teddy can’t help but fall down the same rabbit hole. Teddy’s investigation quickly gets her in hot water with her gun-nut boyfriend, her long-lost half brother, and her colleagues at the prestigious high school where she teaches English. Further complicating matters is Teddy’s growing obsession with Mickey, a charming amateur sleuth who is eerily keen on helping her solve the case. As she struggles to reconcile new information with old memories, Teddy’s erratic behavior reaches a fever pitch, but she won’t stop until she finds Angie.

It was supposed to be the highlight of her career, the pinnacle for which she’d worked all her life. And as Hattie McDaniel took the stage in 1940 to claim an honor that would make her the first African-American woman to win an Academy Award, she tearfully took her place in history. Between personal triumphs and tragedies, heartbreaking losses and severe setbacks, this historic night of winning best supporting actress for her role as the sassy Mammy in the controversial movie Gone with the Wind was going to be life-changing. Or so she thought. Months after winning the award, not only did the Oscar curse set in where Hattie couldn’t find work, but she found herself thrust in the middle of two worlds --- Black and White --- and not being welcomed in either.

Grieving her best friend's recent death, neuroscientist Mariana Pineda is ready to give up everything to start anew. Even her career --- after one last week consulting at a top-secret particle accelerator. Except the strangest thing happens: a man stops her and claims they've met before.

Again. Together, Mariana and Carter enter an inevitable life, four days at a time, over and over, without permanence except for what they share. But just as they figure out this new life, everything changes. Because Carter's memories of the time loop are slowly disappearing. And their only chance at happiness is breaking out of the loop --- forever.

When the Australian Mystery Writers’ Society invited me to their crime-writing festival aboard the Ghan, the famous train between Darwin and Adelaide, I was hoping for some inspiration for my second book. Fiction, this time: I needed a break from real people killing each other. Obviously, that didn’t pan out. The program is a who’s who of crime-writing royalty: the debut writer (me!), the forensic science writer, the blockbuster writer, the legal thriller writer, the literary writer, and the psychological suspense writer. But when one of us is murdered, the remaining authors quickly turn into five detectives. Together, we should know how to solve a crime. Of course, we also should know how to commit one. How can you find a killer when all the suspects know how to get away with murder?

To finally end the war between their nations, a rogue band of Ukranian partisans known as the Wolves teams up with members of Russia’s military intelligence to assassinate Vladimir Putin. But Putin is aware of the traitors in his midst and assigns the loyal commander of the Russian National Guard to root them out. It’s a mission Victor Petrov is expected to undertake after he prevents Sweden from joining NATO --- by assassinating a deputy minister of foreign affairs. After receiving intelligence about the threat in Sweden, the United States sends Pike Logan to identify Petrov’s target --- only for him to get caught in the crossfire. When the smoke clears, Pike makes no effort to stop the Wolves on their ultimate mission, believing it just, until he discovers that their operation has unimaginable consequences.
