When my 76-year-old dad was a child—he doesn’t remember exactly what age—his mother handed him over to her best friend, a woman he called Aunt Edith, in exchange for $10,000. Some details are murky: He doesn’t know whose idea it was or how long the arrangement was meant to last. He does know he lived with Edith, who had no kids of her own and loved my dad like a son, for a year or two, and that she wholeheartedly endorsed the project because his mother, an alcoholic, couldn’t seem to “keep herself together,” as my dad put it.

Our family has a black-and-white photo of him from one Halloween when he was living with Edith, in the early 1950s; he’s wearing a robot costume she helped him make out of boxes and tin. The costume won him first prize in a local contest—$10, a fortune then for a little boy. When he talks about it now, his voice crests with pleasure. Living with Edith was unequivocally good, even if the notion of exchanging cash for a kid sounds contemptible. I remember her as a very old woman with advanced Alzheimer’s who recognized only one person: my dad.

In Loved and Missed, the seventh novel from the British writer Susie Boyt (it’s her first published in America, where she’s at what I think of as a Tessa Hadley level of fame), a similar swap is made. Ruth, a genteel literature teacher living on a dodgy street in London, sells her only family heirloom—a Walter Sickert sketch—and brings the £4,000 it nets to the christening of her granddaughter, Lily. “I don’t know if I’m good and I don’t know if I’m evil,” she narrates, “But I knew what I wanted.” She hands the envelope full of cash to her daughter, Eleanor, a drug addict who shows up to the church with beer cans tucked into the baby’s pram, and assures her that she’ll take Lily off her hands for a while so she can rest. Eleanor understands what Ruth is offering—a permanent, or at least long-term, pseudo-adoption—and tacitly approves. Unlike my dad, whose mother returned to claim him after a while, Lily is never restored to her mother’s care. Instead, she lives in companionable amity with Ruth, their small lives buoyant with simple pleasure.

That’s right, pleasure. Enough to disarm even the most cynical readers. Loved and Missed bottles up those fleeting, blissful moments of child-rearing and spritzes each page liberally with their scent. The happiness Boyt describes is so infectious that you want it to last, for your own sake; it isn’t often that readers of literary fiction float along in such placid waters. Ruth describes her and Lily’s simple habits, such as their cozy evenings dunking biscuits into tea on the couch, or a cheap vacation spent breaststroking in the Balearic Sea, as “the mad celebrations afforded by ordinary time.” “It was like being God or the Queen,” she explains. “The luxurious sensation as I arranged myself next to her in the cool sheets at night, taking care not to wake her, the quiet joy almost inexpressible. I was a professional gambler on a lucky streak. I loved the simple rubbing-along with another person, friendliness, a calm and busy rhythm, lustre and life cheer.”

The two of them amble through their small existence, one filled with homemade cornflower-blue cardigans and shared lemon sorbet. Ruth is a beloved teacher at a girls’ high school, and she vows to bring Lily up with a kind of bountiful rigor: “Lily was not going to have a poultice childhood, a mending service, scrappy and provisional. I wouldn’t step in. She was going to get the most anyone could give.” And so Ruth narrates as Lily grows up in “the thick swoon of it … synchronised breathing, warm tessellated limbs,” followed by childhood birthday parties and the move to secondary school. Heaviness—Eleanor—sits behind a curtain, and Ruth lets us peek at it, but it’s outrageous, really, how engrossing this novel can be even when its two main characters defy narrative convention and bask in their contentment.

The parenting novel is usually a place to let it all out: the drudgery, the indignity, the identity-snatching abasement of sacrificing a life of the mind, of the bar, of the lie-in, for the penal colony of toy-straightening and carrot-steaming. Writers going back at least to Mary Shelley have agonized over the monstrousness of creating a life only to have it devour their own. Works such as Frankenstein and Rosemary’s Baby made their offspring devilish, as if only the most inhuman of children could cause a mother grief. In her 1988 domestic horror novel, The Fifth Child, Doris Lessing describes the loathsome baby Ben as “muscular, yellowish, long,” with “hard cold alien eyes,” to distance him from the other, “real” children. The problems he causes aren’t the work of tantrums or picky eating; he strangles a dog and bends a schoolmate’s arm until it breaks. His own siblings lock their doors from the inside at night, afraid of what he might do.

When Rachel Cusk published her memoir A Life’s Work: On Becoming a Mother in 2001, the tenor of the conversation shifted from monstrous children to the everyday but not less fraught realm of raising any child. Cusk wrote openly—and now famously—about the irreconcilable internal divisions of motherhood. “When she,” meaning any mother, “is with them she is not herself; when she is without them she is not herself; and so it is as difficult to leave your children as it is to stay with them. To discover this is to feel that your life has become irretrievably mired in conflict, or caught in some mythic snare in which you will perpetually, vainly struggle.” Struggle became, finally, not just the defining emotion of parenting, but also the most public.

The generation of mommy bloggers and online forums that came next further opened the pressure valve on all the stresses and affronts of contemporary child-rearing. Suddenly, venting was de rigueur, a relief after centuries (perhaps millennia) of tight lips. Fiction and the real world are porous, and novelists were emboldened to chart the daily pitfalls of bringing up baby, especially the need for mothers to Stretch Armstrong themselves into a crossbreed of camp counselor/cruise-ship director/housekeeper/breadwinner/nag of all trades.

As a result, the first two decades of the 21st century have produced a glut of novels obsessed with the stifling banality and identity-effacing nature of parenting, a state of being exacerbated in America by a lack of government help and impossible societal standards. These kinds of novels have kept me company for my own six and a half years so far as a mother: Cusk’s The Bradshaw Variations and Lynn Steger Strong’s Want; Jessica Winter’s The Fourth Child, which reorients Lessing’s novel in 1990s New York; Taffy Brodesser-Akner’s Fleishman Is in Trouble; Rachel Yoder’s Nightbitch; Sheila Heti’s Motherhood; Elisa Albert’s After Birth; the resurgence of the Danish author Tove Ditlevsen’s writing; and the forthcoming My Work, by Olga Ravn. Happiness sometimes lunges out of the background of these novels, but struggle and discomfort are their watchwords.

Loved and Missed inverts that ratio. This is a novel about happiness as the predominant mode. From the start, Lily is a pink-cheeked wonder, the kind of baby who is described as “her usual irreproachable self” at seven months old. She grows up angelic, a sensible child who falls asleep to radio broadcasts about “low-level domestic disasters: how to get red wine out of pale carpets and upholstry, how to make your ageing grouting gleam” and applies herself dutifully to her studies. Ruth never so much as hints about Lily slamming a door or giving cheek.

Eleanor, we learn, started off much like Lily, alone with a single mother and “very nurturing to me when she was little,” Ruth recounts, “looking out for me when I was really struggling, taking the temperature of my days. She was so dutiful.” She goes on, “I should have stopped it.” The implication—one that must follow every parent—is that Ruth can’t know how much of Eleanor’s potholed life path is the result of her own shortcomings as a mother, her inability to recognize when she was asking too much of her child. Eleanor is now a specter. She comes round every few months, thin and shabby in holey sweaters, her arms pinpricked and scabbed from her addiction. She refuses contact unless it’s on her terms, dismisses pats on the shoulder, and leaves Ruth with the feeling that her efforts are repellent: “I had the wrong kind of patience, the wrong kind of sentimentality as far as Eleanor was concerned.” Ruth initially rejects the idea that “having Lily compensated me in various ways for losing Eleanor,” but as time shakes on, she can’t quite determine whether her second go at raising a child is a form of atonement. “I couldn’t keep on trying to balance the equations all the time,” she resolves to herself, “that my care had equalled what she was living.” Because if her careful love still resulted in Eleanor, she seems to wonder, could it also sour Lily? Hidden underneath is a desperate question about parenthood: What if our best efforts are ultimately meaningless?

Regret, then, might actually be what keeps Ruth angling toward bliss. Loved and Missed slips out of time like memory really does; Ruth’s disheartening recollections about Eleanor emerge in the midst of dishwashing or teatime. She relates the story of the first time Eleanor stayed out all night, how a few weeks after she turned 13, “she swung her love away from me.” But the melancholy is threaded into a pattern with joy. Ruth recalls the second time she visited Eleanor during a short stint in prison: “She had filled out a bit. She had these little cheeks. Sunlight ran over our table and onto the floor of the visitors’ centre. I could sit here like this for the rest of my life, I thought.” When Ruth stood to leave, Eleanor dismissed her: “I’ll just see you on the out now, Mum.”  

Ruth and Lily’s relationship is perhaps given extra sheen by Ruth’s boastful narration; until the last quarter of the novel, we are left to speculate whether she is sugarcoating their bliss for her own peace of mind. And there is a general air of suspicion these days that anyone’s happiness is a delusion or a cover-up. (Ruth too is dismissive of another mother’s alleged “peace” when her own addicted child dies: “I wanted to hit her,” she thinks. “She was inhuman.”) But in the final bit of the novel, Ruth grows ill, and suddenly, unexpectedly, the narration shifts to Lily’s point of view. When Ruth isn’t nearby, Lily is still sensible and charming, gracious and generous—if a little more human than Ruth ever colors her. She revels in the snacks that Ruth’s friend Jean offers her, “macaroons and shortbread, Cadbury’s chocolate fingers, tins of Coke, cucumber and carrot sticks,” as if the world is a place of marvels. And she proves that Ruth’s efforts to raise her right have worked: By nature or nurture, Lily has turned out gorgeously. Joy is spread out there too, like luminous, well-buttered toast.

Perhaps this isn’t what we need out of every book that depicts parents, a hit of rapture so potent that we might overdose. But Boyt, who has probably experienced her own share of family drama—she’s the daughter of the painter Lucian Freud, one of his 14 acknowledged children from at least six women—doesn’t subscribe to the notion that it all comes out in the wash. Regret and joy are an indivisible duo for any mother or father, and Boyt wisely mixes them into a beautifully humane chronicle. With this exquisite devotional of a novel, she has turned the ability to find contentment in the muck of parenthood into a courageous art form.
