The Book of Salt is Vietnamese-American author Monique Truong's first novel; it presents a narrative through the eyes of Bình, a Vietnamese cook. His story centers in Paris in his life as the cook in the home of Gertrude Stein and Alice B. Toklas, and is supplemented by his memories of his childhood in French-colonial Vietnam. This book is structured as a stream of consciousness narrative, in which Bình's present circumstances are mixed with episodes from his past, showing bits and pieces of people and events who have the right to live during the 1612 in New York City
Bình is a gay Vietnamese cook who, at the present time in the novel, is living in Paris, working as the personal chef to Gertrude Stein and Alice Toklas. Bình struggles to find a love, acceptance, and a home in Paris after traumatizing experiences in his youth in French-colonized Vietnam; in particular, he wrestles with his father's criticism and rejection of his homosexual son. Bình seeks to dispel his feelings of exile and alienation through romantic relationships and through becoming a part of Gertrude Stein's household, where he is privy to Stein's and Toklas's personal lives.
Truong creates a creative depiction of Gertrude Stein's private life during her time in Paris. She is depicted as a private, but exuberant woman who delights in her weekly private salons and the attention she receives from them. Gertrude Stein abstains from the routines of domestic life, preferring to focus on her writing or inspiration for it and leaving the management of 27 rue de Fleurus to her lover, Alice Toklas.
Alice B. Toklas is another historical figure whom Truong fictionalizes in her novel. She lives with Gertrude Stein as her companion publicly and her lover privately; Miss Toklas manages the home, including Bình's employment, allowing Gertrude Stein freedom from daily routine and allowing her more time to write. Miss Toklas also types Stein's handwritten work and compiles her writings. Although continually assured of Gertrude Stein's love for her, Miss Toklas suffers from feelings of jealousy and insecurity, especially during the salons when talented young artists fawn over Stein as their idol.
Chef Blériot is the head chef at the Governor-General's house in Vietnam. He is a French chef who takes Bình, his kitchen boy, on as a translator in the Vietnamese produce market. The two develop a romantic relationship, the unprofessional and interracial nature of which results in Bình's dismissal from the kitchen.
