Frederica is a Regency romance novel by Georgette Heyer. The story is set in 1818. The plot is typical of several later Heyer romances in counterpointing the courtships of an older and a younger couple, with variation provided by the antics of Frederica's younger brothers and their boisterous mongrel. Plot summary A wealthy bachelor's affluent sisters, whom he dislikes, lobby him to give a ball at his own expense for their daughters' come-out. A distant cousin also asks him to introduce her attractive younger sister to the ton. To the astonishment of all, he agrees to give the ball on condition that his encroaching sisters share it with their unknown cousins. His sisters assume he must be under the spell of the beautiful younger cousin, whereas it is the seemingly unremarkable older cousin, encumbered with raising her three orphaned younger siblings and managing a neglectful older brother, who has caught his carefully concealed interest.

At their combined debut ball, Alverstoke's homely niece is easily outshone by Charis' beauty. The Merrivilles are liked by everyone for their easy and engaging manners and good breeding. Charis is admired by many young men but she falls for the Marquis's slow-witted and handsome cousin Endymion Dauntry. Frederica also acquires her own share of admirers, including (to his own astonishment) Alverstoke himself. Alverstoke is fascinated by her frank and open manners, unlike the society manners of London's fashionable ladies. He is also delighted by the high spirits of the two youngest Merrivilles, her brothers Felix and Jessamy, and comes to like them for their own sakes. He slowly but deeply falls in love with Frederica and is ready to
