What happens when a professional chef becomes a dominatrix, swapping the heat of the kitchen for the intensity of a dungeon? A memoir in three parts, Concertina spans five years of the author's life as she makes the extraordinary transition from culinary expert to professional dominatrix. Taking the reader into the secret, hidden world of suburban sado–masochism, Winemaker introduces us to a fascinating array of colourful characters, before she breaks the code of domination: falling in love with a client.

Honest, brave and beautifully written, Concertina is a memoir that finds passion and tenderness in the most unlikely places.

"...rich, layered, funny, tragic and mature beyond its years." —Chatelaine

"...lyrical, poignant, and multi-layered, like a delicate pastry, or perhaps more like an onion, the increasingly sharp layers of which can sometimes make your eyes sting but that you know will add intense flavour to your dish." —The Globe and Mail
