What is the author's style in In the Company of the Courtesan: A Novel by Sarah Dunant?

In the Company of the Courtesan is told through the eyes of Bucino, the dwarf who tells of his life with the courtesan Fiammetta. As the story is told through the first-person perspective, the reader sees the events unfold as Bucino sees them. Interestingly, Dunant does not choose to share the character's identity with us or even his gender until mid-way through the first lengthy chapter. Thus, the reader begins the book expecting a traditional narrative and is surprised to identify with a character who would usually be dubbed an outsider.
