A Study in Sparkling Summary: Fiona & Satoshi’s Age-Gap Romance
Introduction
Fiona Fisher has been a regular at Tsundoku — a Hobart wine bar and second-hand bookstore — since the day it opened.
Its owner, twenty-seven-year-old sommelier Satoshi Tsukamoto, fell in love with her somewhere between a broken tray of glasses and a chaotic Tuesday-night rush.
Then Fiona’s husband announces he has kept a secret second family in Melbourne for a decade, and her carefully ordered life unravels.
A Study in Sparkling, Jodi McAlister’s contemporary romance, traces the ten months after her divorce, when a blind tasting in a back office pushes two careful people past the line between friends and something more.

A Study in Sparkling Summary: The Full Story
Major spoilers ahead — including the ending.
Jodi McAlister opens her novel two years before the main timeline. Satoshi pours his inheritance into Tsundoku, an urban cellar door for his brother Isamu’s Bibliophile Wines, fused with a second-hand bookshop.
Fiona walks in as one of his first customers and becomes a fixture.
On a chaotic Tuesday, she steps behind the bar during a glassware disaster and runs the floor beside him. Satoshi falls in love that night.
Hours later she returns shaking: her husband Matt has confessed to a secret second family in Melbourne and is leaving her and their three children.
One year on, Fiona faces Matt in mediation with her divorce lawyer Kavita and corporate-lawyer sister-in-law Chess, who uncovers his offshore accounts and shell companies.
She wins proper child support and structured visitation. Worn out, she goes to Tsundoku — the one place Matt never touched.
During a blind tasting in the back office, Satoshi tells Fiona she deserves pleasure, and they cross a line before a knock at the door sends her fleeing.
The next evening at a restaurant, he corners her in a corridor to insist his desire is genuine.
Fiona, afraid of losing his steadiness in her child Lex’s life and dreading school-gate gossip, asks to go slowly. Satoshi proposes “high school rules”: hand-holding, cuddling, and kissing, nothing rushed.
He becomes her study buddy for the Introductory Sommelier course and mentors her wine writing.
The arrangement works. Fiona passes her exam and wins the New Viniferous Voices competition with a profile of Bibliophile Wines.
But Matt keeps pushing — showing up unannounced on Boxing Day until Lex breaks down — and a confrontation at his rental gives Fiona clarity: he left out of financial cowardice and greed.
That night she walks into an empty Tsundoku and asks Satoshi for “all of it.” They spend the night together and commit to something real.
In January the bar buckles: Birdie resigns, the glasswasher fails, and Satoshi grinds through brutal shifts while training for the Australian Young Sommelier of the Year competition.
Burnout catches up with him in intimate and professional ways.
At Jonah and Sadie’s wedding, Fiona’s father belittles Satoshi’s career, and a stray comment from Satoshi’s ex reminds Fiona that he once wanted marriage and children of his own. Convinced she is trapping him, she ends it — and he faints on the cellar-door floor.
Isamu forces Satoshi to rest and takes over the bar. Lex confronts Fiona, pointing out that Satoshi loves her, the children love him, and they come as a package deal.
Fiona confesses her love upstairs at Tsundoku; Satoshi answers that loving her and her kids already fulfills the family he wants.
Months later, in August, Satoshi passes his Master Sommelier theory exam in Paris. Over a video call, Jonah and Sadie announce a pregnancy.
At a Montmartre cafe with Bandol rosé, Fiona asks him to move in with her, the three kids, and his cat Yquem.
He says yes, and A Study in Sparkling closes on that toast.

Is A Study in Sparkling Right for You?
This book suits readers who like contemporary rom-coms built on friends-to-lovers slow burns, single-parent heroines, and noticeable age gaps between leads.
It pairs open-door intimate scenes with domestic stakes such as divorce mediation, co-parenting, and school-gate gossip.
The experience is character-driven rather than plot-driven: ten months unfold through monthly headers, alternating first-person chapters, and interludes of texts and emails.
Readers drawn to wine and hospitality detail, Australian settings, and steamy banter will find plenty of both here.
