THE NATURE OF NEGATIVE NUMBERS

Erickson delves into the nature of numbers, what they are, how we have formulated them throughout history, where we’ve gone wrong and how we can fix it.

In this numeric exploration, Erickson exposes inconsistencies in the way the real number system has been structured. Starting from the nature of real numbers together with their basic operations such as subtraction and multiplication of signed numbers, Erickson finds that there are flaws in how we view negative numbers; their roots lie both in our structure of the number line and the notion that the removal of a deficit is equivalent to giving a gift. To resolve these issues, the author presents his own number system, what he terms the “veritable” number system. Common operations such as subtraction, logarithms and trigonometric functions no longer work as they used to, and Erickson spends much of the remainder of the book showing us how to do these operations using his veritable numbers. But since essentially all of mathematics and the sciences are rooted in the real numbers with their own (different) laws, functions and operations, the author’s new number system is not particularly practical. Erickson rounds out the book discussing a few other topics, such as polar coordinates and Hamilton’s discovery of the quaternions. The author’s ideas and reasoning are compelling, and his discussions about imaginary numbers and how he unifies them via the use of both the real numbers and his veritable numbers, together with his desire to remove the “mystery” behind these concepts, should carry the interest of most mathematically inclined readers. A fascinating look at some of the underlying issues behind numbers—negative numbers in particular—though perhaps more as a curiosity than for practical application.

SUMMER ISLAND

Talk-show queen takes tumble as millions jeer.

Nora Bridges is a wildly popular radio spokesperson for family-first virtues, but her loyal listeners don't know that she walked out on her husband and teenaged daughters years ago and didn't look back. Now that a former lover has sold racy pix of naked Nora and horny himself to a national tabloid, her estranged daughter Ruby, an unsuccessful stand-up comic in Los Angeles, has been approached to pen a tell-all. Greedy for the fat fee she's been promised, Ruby agrees and heads for the San Juan Islands, eager to get reacquainted with the mom she plans to betray. Once in the family homestead, nasty Ruby alternately sulks and glares at her mother, who is temporarily wheelchair-bound as a result of a post-scandal car crash. Uncaring, Ruby begins writing her side of the story when she's not strolling on the beach with former sweetheart Dean Sloan, the son of wealthy socialites who basically ignored him and his gay brother Eric. Eric, now dying of cancer and also in a wheelchair, has returned to the island. This dismal threesome catch up on old times, recalling their childhood idylls on the island. After Ruby's perfect big sister Caroline shows up, there's another round of heartfelt talk. Nora gradually reveals the truth about her unloving husband and her late father's alcoholism, which led her to seek the approval of others at the cost of her own peace of mind. And so on. Ruby is aghast to discover that she doesn't know everything after all, but Dean offers her subdued comfort. Happy endings await almost everyone—except for readers of this nobly preachy snifflefest.

The best-selling author of tearjerkers like Angel Falls (2000) serves up yet another mountain of mush, topped off with syrupy platitudes about life and love.

THE VANISHING HALF

Inseparable identical twin sisters ditch home together, and then one decides to vanish.

The talented Bennett fuels her fiction with secrets—first in her lauded debut, The Mothers (2016), and now in the assured and magnetic story of the Vignes sisters, light-skinned women parked on opposite sides of the color line. Desiree, the “fidgety twin,” and Stella, “a smart, careful girl,” make their break from stultifying rural Mallard, Louisiana, becoming 16-year-old runaways in 1954 New Orleans. The novel opens 14 years later as Desiree, fleeing a violent marriage in D.C., returns home with a different relative: her 8-year-old daughter, Jude. The gossips are agog: “In Mallard, nobody married dark....Marrying a dark man and dragging his blueblack child all over town was one step too far.” Desiree's decision seals Jude’s misery in this “colorstruck” place and propels a new generation of flight: Jude escapes on a track scholarship to UCLA. Tending bar as a side job in Beverly Hills, she catches a glimpse of her mother’s doppelgänger. Stella, ensconced in White society, is shedding her fur coat. Jude, so Black that strangers routinely stare, is unrecognizable to her aunt. All this is expertly paced, unfurling before the book is half finished; a reader can guess what is coming. Bennett is deeply engaged in the unknowability of other people and the scourge of colorism. The scene in which Stella adopts her White persona is a tour de force of doubling and confusion. It calls up Toni Morrison’s The Bluest Eye, the book's 50-year-old antecedent. Bennett's novel plays with its characters' nagging feelings of being incomplete—for the twins without each other; for Jude’s boyfriend, Reese, who is trans and seeks surgery; for their friend Barry, who performs in drag as Bianca. Bennett keeps all these plot threads thrumming and her social commentary crisp. In the second half, Jude spars with her cousin Kennedy, Stella's daughter, a spoiled actress.

Kin “[find] each other’s lives inscrutable” in this rich, sharp story about the way identity is formed.
