It's in His Kiss

The seventh installment in Julia Quinn's Bridgerton series, set in Regency-era England, follows the romance between Hyacinth Bridgerton, the youngest of eight siblings in a prominent aristocratic family, and Gareth St. Clair, a charming rake burdened by a devastating family secret.

The novel opens with a prologue set in 1815. Eighteen-year-old Gareth is summoned home from Eton by his father, Lord St. Clair, a baron who has always treated him with contempt. The baron orders Gareth to marry Mary Winthrop, the intellectually disabled daughter of a neighboring earl, because her generous dowry will rescue the family from financial ruin. Gareth refuses the match as unconscionable. Enraged, the baron reveals a secret kept for eighteen years: Gareth is not his biological son but the product of his late wife's affair with an unknown man. Lord St. Clair cuts Gareth off financially, ending his support and his plans for Cambridge. Gareth walks away, beginning a decade-long estrangement.

Ten years later, the story proper begins at the annual Smythe-Smith musicale, a London event infamous for its dreadful amateur music. Hyacinth Bridgerton, now in her fourth season, sits in the front row with her sister-in-law Penelope and the elderly Lady Danbury, a sharp-tongued countess who is Gareth's maternal grandmother. Hyacinth is witty and outspoken, but she receives fewer marriage proposals each year. Gareth arrives, guilted into attending by his grandmother, and takes the seat beside Hyacinth. Their quick-witted banter throughout the concert leaves Hyacinth unsettled; she finds him impossible to read, and his teasing farewell kiss on her hand renders her speechless for the first time in memory. Gareth's private reflections reveal his precarious situation: after his older brother George's death nearly a year earlier, Gareth became the St. Clair heir, and he lives in constant expectation that the baron will publicly denounce his parentage.

A few days later, George's widow, Caroline, brings Gareth a leather-bound diary that belonged to his paternal grandmother, Isabella Marinzoli St. Clair. The diary is written entirely in Italian. Gareth takes it to Lady Danbury for help, and Hyacinth, present for her regular Tuesday reading visit, reveals she learned some Italian from a childhood governess. She begins translating and discovers that Isabella was deeply unhappy about her forced marriage at seventeen. Gareth entrusts the diary to Hyacinth, and they agree to continue meeting to discuss her progress.

At home, Hyacinth's mother, Violet Bridgerton, delivers a personal revelation: on the day Hyacinth was born, shortly after the death of Hyacinth's father, Edmund, the infant's arrival prompted Violet's first smile since her husband's death. Violet gently warns Hyacinth that she pushes away men who are her intellectual equals because she is uncomfortable when she does not feel in complete control. Hyacinth is shaken and promises to consider the observation.

Over the following days, Gareth and Hyacinth's connection deepens at shared social events. At a Bridgerton ball, Hyacinth spots Lord St. Clair and asks Gareth to dance to prevent a confrontation between father and son. During their waltz, they share a vulnerable moment about their respective absent fathers. Afterward, Gareth encounters the baron privately. Lord St. Clair taunts him, insisting Hyacinth will never marry him and speculating that Gareth's real father was a servant. Shaken and furious, Gareth encounters Hyacinth in the hallway and kisses her with desperate intensity. His offhand remark that she needs kissing lessons stings her deeply, and she runs away, humiliated by her first kiss.

Despite her hurt, Hyacinth continues translating and makes a breakthrough. Isabella wrote about hiding jewels, including diamonds and a bracelet brought by her Italian grandmother, somewhere in Clair House, the St. Clair London residence. Hyacinth argues they must retrieve the jewels before Lord St. Clair finds them. Gareth resists bringing her along, but Hyacinth insists her Italian is essential, and he reluctantly agrees to a midnight expedition. Following a clue about an armadio (a cabinet or wardrobe), they discover a secret compartment containing not the jewels but another clue written by Isabella. They narrowly avoid detection by the baron's butler and escape into the night, their camaraderie deepening.

During a walk in Hyde Park, Gareth confesses that his grandmother is the only person in the world he loves and says he would give anything to have one more person for whom he would lay down his life. Hyacinth realizes with sudden clarity that she wants to marry this man. Back at her home, Gareth kisses her tenderly, and this time the kiss is everything the first was not: gentle, deliberate, and deeply felt. He resolves to marry her, motivated by genuine affection and, he privately admits, the satisfying thought of defying his father.

Gareth proposes at Lady Danbury's during Hyacinth's Tuesday visit, dropping to one knee before both Hyacinth and his grandmother. Lady Danbury shouts "Yes!" before Hyacinth can speak, but Hyacinth tearfully accepts. Gareth then secures permission from Hyacinth's eldest brother, Anthony Bridgerton, who tells Gareth that marrying Hyacinth means gaining the entire Bridgerton family.

During a subsequent visit to Clair House, Lord St. Clair confronts them on the street. The baron reveals that Gareth is still legally betrothed to Mary Winthrop and claims he manipulated Gareth into proposing to Hyacinth through reverse psychology. Hyacinth overhears every word and flees. In their most devastating argument, she declares that Gareth proposed only to spite his father and that the proposal had nothing to do with her. She asks him to leave, saying she regrets giving herself to him.

Three painful days of separation follow. Hyacinth agonizes but realizes she would stay even if she could leave: She loves him, and his feelings for her are genuine, however tangled his motives. She goes to Gareth's apartments, and they reconcile. Gareth confesses the truth about his birth, telling her Lord St. Clair is not his biological father. Hyacinth's reaction is characteristically practical: She expresses relief that her children will not carry the baron's blood and declares the secret changes nothing. Gareth gives her two drawings he has made, one depicting her wearing a diamond bracelet from Isabella's stories. Hyacinth is deeply moved, recognizing the gift as more precious than actual jewels.

On the following Tuesday, Hyacinth skips ahead in Isabella's diary to 1796 and discovers that Lord St. Clair was away for months while his wife became pregnant. Isabella deduced that the father was Edward St. Clair, the baron's younger brother, who had been staying at the family estate that summer. Hyacinth races to Gareth at midnight. Furious that she has again traveled alone at night, Gareth blurts out that he loves her. Hyacinth reveals the truth: Isabella really was his grandmother, he is a St. Clair by blood, and the uncle who always showed him special kindness was his father. They make love for the first time.

They return to Clair House, where they find nothing in the bedchamber but locate a book referenced in Isabella's earlier clue containing yet another note in an unknown language. On the street, Gareth encounters his father. Feeling free for the first time, he calmly tells the baron the truth about Edward. Lord St. Clair turns white, says almost nothing, and goes inside. Gareth drops to one knee and proposes to Hyacinth again, this time explicitly because he loves her. She joyfully accepts.

The epilogue traces the years that follow. The Winthrop betrothal is resolved without difficulty. Gareth and Hyacinth marry at St. George's in London and have two children: a son named George and a daughter named Isabella. After Lord St. Clair dies, Gareth inherits the title and Clair House. Hyacinth searches obsessively for the jewels for years without success. Unknown to her parents, ten-year-old Isabella discovers the diamonds hidden behind a tile in the nursery washroom and secretly keeps them. A second epilogue set in 1847 brings the story full circle. Overcome with guilt after overhearing her mother still searching, Isabella secretly returns the jewels. One year later, Hyacinth finally discovers them, and her triumphant shout brings Gareth running. He slips the ring onto her finger, completing the quest that has defined decades of their lives. One floor below, Isabella hears her mother's cry of joy, turns back to her book, and smiles.
