Romancing Mister Bridgerton

Romancing Mister Bridgerton is a 2002 historical romance novel written by Julia Quinn and published by Avon. It is the fourth novel of Quinn's series of Regency romances about the Bridgerton siblings and tells the story of Colin, the third eldest child of the family.

The novel has been a New York Times, Apple Books, USA Today, and Publishers Weekly bestseller, both at the time of publishing and after the debut of the TV adaptation nearly twenty years later. It has been adapted as the third season of Netflix's Bridgerton series, one of the platform's most popular shows of all time. After the show began airing, book retailers often sold out of the series and hardcover copies of the original books began re-selling at prices as high as $700.
