"Cotillion" is a novel written by Georgette Heyer, set in the Regency era of England. The story revolves around the spirited and independent protagonist, Kitty Charing, who finds herself under pressure to marry. Her wealthy guardian, Sir Henry, intends to bequeath his fortune to her but only if she marries one of several suitors he has in mind. Kitty, however, desires to escape and assert her independence, leading her to hatch a plan that requires her to become engaged to a man of her choosing, albeit one she initially sees as a less-than-ideal match.
The narrative explores themes of love, societal expectations, and personal freedom, as Kitty enters into a faux engagement with the charming and roguish Jack Westruther. As the plot unfolds, readers are treated to witty dialogue and delightful misunderstandings typical of Heyer's works. Kitty's journey takes her through various social events and encounters, allowing her to navigate the complexities of relationships and the pressures of conformity within the upper-class society of the time.
