Warning: Possible spoilers ahead. Netflix’s Bridgerton is based on the book series of the same name by American romance author Julia Quinn. Each of the Bridgerton books, written between 2000 and 2006, follows the lives of one of the eight Bridgerton siblings as they find love matches spanning across Regency-era England—from 1811 to 1820—and slightly beyond, under the watchful eye of London’s elite society. [time-brightcove not-tgx=”true”] The show takes a lot of liberties with the book characters and plots but generally stays true to the central theme of each book.
