By all measures, 23-year-old Mariana is a success story.

Several fatal recent accidents involving Amtrak passenger trains have raised concerns over rail safety, and one of the places most involved in helping railroads become safer is at Virginia Tech.

Mandalay Bay hotel of Las Vegas will eliminate its 32nd floor by the end of this week, from where gunman Stephen Paddock rained bullets on ground in October last year, killing 58 and wounding more than 500 others.

My first CES post told the story of my adventure through today’s new tech for learning. I had an amazing time meeting entrepreneurs and seeing their innovations in action. Hosting a panel as part of the Kids@Play program was a great way to connect with these businesspeople.

In his book “Show Me the Evidence: Obama’s Fight for Rigor and Results in Social Policy,” Ron Haskins described a quiet revolution that took place during the Obama administration in the way that social service programs were evaluated and funded.

A novel written in the English language with a name like An American Marriage conjures up a specific set of broad outlines: post-war optimism, masturbation in the suburbs, the disappointment of life, familial breakdown, that sort of thing. “White people in Connecticut getting a divorce,” author Tayari Jones supplies dryly, from the fringe of a migraine, when I begin to ask her about the title of her newest novel. It was a yoke she was keen to sidestep, even though she was the one who suggested it in the first place.

Feel Free, by Zadie Smith (Penguin Press, Feb. 6)
Smith is as famous for what she thinks as what she makes up. In this new collection of essays her subjects range from highbrow to low- (Knausgaard to Bieber), from politics (Brexit) to tech (Facebook), and from the arcane (Schopenhauer) to the personal (her father). Feel Free is a shepherd’s pie of nonfiction whose only through line is a writer unafraid of getting lost, because she always knows the way home. Smith has mixed it up with critics since she herself was a wunderkind with a giant advance, but age hasn’t hardened her against the world, only made her more porous.

Most stories are, in one way or another, about love. With Valentine’s Day approaching, I sifted through my pile of new releases to find some especially appropriate reads for this most romantic of holidays: a poignant novel about marriage, an essay collection about relationships, a thriller of love-gone-wrong, and a charmingly high-tech rom-com. All are worth a read, with open hearts.

IN 2009, four years after the release of her second novel, The Untelling, Tayari Jones found herself without a publisher. Her sales numbers were hardly strong—in fact, she says, she had become “radioactive.” “I was so depressed,” Jones, 47, says. At the time, she had begun work on a new novel, which would eventually become the best-selling Silver Sparrow. “The only reason I kept working on Sparrow was because I tell my students that you write a book for you and not your publisher. I couldn’t face them every day if I were to give up on that project.” She finally completed the manuscript with the help of a grant from the United States Artists Foundation; later, at a reading in Florida at the Key West Literary Seminar, an admirer came up to Jones to express outrage that she still didn’t have a publisher. The admirer introduced Jones to an executive at Algonquin Books, which would go on to publish Silver Sparrow and Jones’s latest book, An American Marriage. After inquiring about her novel, the executive asked, “But how do you know Judy?” Jones’s admirer had been none other than literary icon Judy Blume.
