The Vignes twin sisters will always be identical. But after growing up together in a small, Southern black community and running away at age 16, it's not just the shape of their daily lives that is different as adults, it's everything: their families, their communities, their racial identities. Ten years later, one sister lives with her black daughter in the same Southern town she once tried to escape. The other secretly passes for white and her white husband knows nothing of her past.

Chaurisse and Dana have a lot in common. They both grew up in Atlanta, they shop at the same stores, visit the same restaurants. But unlike Chaurisse, Dana knows the truth: that the girls share the same father. A father with two families, one of which he is determined to keep secret. When the girls meet and become friends, the unsteady balance of both their lives is threatened. Theirs is a relationship destined to explode. 

14-year-old Adunni has a dream: to be educated. But her father needs her bride-price, so sells his daughter to an older man, who demands she give him the fine boy-children his first two wives have failed to produce. When things go tragically wrong, Adunni flees to Lagos. It's what she has always wanted, to leave Ikati and see the world, and though her heart is full of sorrow for her lost family and the shame she has left behind, still Adunni will not be quiet and do as she's told.

Fifteen-year-old Ana Canción never dreamed of moving to America, the way the girls she grew up with in the Dominican countryside did. But when Juan Ruiz proposes and promises to take her to New York City, she must say yes. It doesn't matter that he is twice her age, that there is no love between them. Their marriage is an opportunity for her entire close-knit family to eventually immigrate. So on New Year's Day, 1965, Ana leaves behind everything she knows and becomes Ana Ruiz, a wife confined to a cold six-floor walk-up in Washington Heights.

Jean Swinney is a feature writer on a local paper, disappointed in love and - on the brink of 40 - living a limited existence with her truculent mother: a small life from which there is no likelihood of escape. When a young Swiss woman, Gretchen Tilbury, contacts the paper to claim that her daughter is the result of a virgin birth, it is down to Jean to discover whether she is a miracle or a fraud. But the more Jean investigates, the more her life becomes strangely (and not unpleasantly) intertwined with that of the Tilburys.

Annie is not the first love of Graham’s life but she is, he thinks, his last and greatest. Very recently, he has faltered; but he means to put it right. Here they are in marriage, in late middle age, in comfort. Mismatched, and yet so well matched: the bookseller with his appetite, his conviviality, his bigness; the photographer with her delicacy, her astuteness, her reserve. The children are offstage, grown up and scattered on either coast; Graham’s first wife, Frieda, is peaceably in their lives, but not between them. 

Astrid Strick has always tried to do her best for her three children. Now, they're finally grown up - but you could be forgiven for thinking otherwise. Elliott doesn't have any idea who he really is, or how to communicate with his own sons. Porter is, at last, pregnant - but feels incapable of rising to the challenge. Nicky has fled to distant New Mexico, where he's living the bohemian dream. And Astrid herself is up to things that would make her children's hair curl.

Casey has ended up back in Massachusetts after a devastating love affair. Her one constant is the novel she has been writing for six years, but at 31 she is in debt and directionless, and feels too old to be that way - it’s strange, not be the youngest kind of adult anymore. Suddenly Casey finds herself at the point of a love triangle, torn between two very different relationships that promise two very different futures.

In 1973, Moll Gladney goes missing from the Tipperary hillside where she was born. Slowly, her parents - Paddy and Kit - begin to accept that she’s gone forever. But she returns, changed, and with a few surprises for her family and neighbours. Nothing is ever the same again for the Gladneys, who learn that fate cares little for duty, that life rarely conforms to expectation, that God can’t be relied upon to heed any prayer. A story of exile and return, of loss and discovery, of retreat from grief and the saving power of love.

In her youth, Tara was wild. She abandoned her loveless marriage to join an ashram, endured a brief stint as a beggar (mostly to spite her affluent parents) and spent years chasing after a dishevelled, homeless 'artist' - all with her young child in tow. Now she is forgetting things, mixing up her maid's wages and leaving the gas on all night, and her grown-up daughter is faced with the task of caring for a woman who never cared for her. 

It is the evening of 16-year-old Melody's coming of age ceremony in her grandparents' brownstone. Watched lovingly by her relatives and friends, making her entrance to the music of Prince, she wears a special custom-made dress - the very same dress that was sewn for a different wearer, Melody's mother, for a celebration that ultimately never took place. Unfurling the history of Melody's parents and grandparents - from the 1921 Tulsa massacre to post-9/11 New York....

Irrepressible Betty Ramdin, her shy son Solo and their marvellous lodger, Mr Chetan, form an unconventional household, happy in their differences, as they build a home together. Home: the place where your navel string is buried, keeping these three safe from an increasingly dangerous world. Happy and loving they are, until the night when a glass of rum, a heart to heart and a terrible truth explodes the family unit, driving them apart.

The year is 1969. In a housing project in south Brooklyn, a shambling old church deacon called Sportscoat shoots - for no apparent reason - the local drug-dealer who used to be part of the church's baseball team. The repercussions of that moment draw in the whole community, from Sportscoat's best friend - Hot Sausage - to the local Italian mobsters, the police (corrupt and otherwise), and the stalwart ladies of the Five Ends Baptist Church.

On the longest day of the summer, 12 people sit cooped up with their families in a faded Scottish cabin park. The endless rain leaves them with little to do but watch the other residents. A woman goes running up the Ben as if fleeing; a retired couple reminisces about neighbours long since moved on; a teenage boy braves the dark waters of the loch in his red kayak. Each person is wrapped in their own cares but increasingly alert to the makeshift community around them. 

When Emira is apprehended at a supermarket for ‘kidnapping’ the white child she’s actually babysitting, it sets off an explosive chain of events. Her employer Alix, a feminist blogger with the best of intentions, resolves to make things right. But Emira herself is aimless, broke and wary of Alix’s desire to help. When a surprising connection emerges between the two women, it sends them on a crash course that will upend everything they think they know – about themselves, each other and the messy dynamics of privilege.
