What is the title of the longest novel to win the Booker Prize?

The Luminaries is the longest novel to win the Booker Prize, taking the 2013 award for its author, Eleanor Catton.

Set in New Zealand’s South Island goldfields in 1866, the novel follows prospector Walter Moody after he arrives in Hokitika and encounters a secret gathering connected to a series of crimes. Catton structures the book around astrology: twelve central male characters correspond to the signs of the zodiac, while another group reflects the planets.

Booker coverage commonly gives the winning novel’s length as 832 pages, although page totals vary between editions and formats. That distinction explains why different sources may quote a slightly different number while still identifying The Luminaries as the record-holder by printed length.

Catton was 28 when she won, making her the youngest Booker winner at the time. The victory also made her only the second New Zealand author to win, following Keri Hulme’s 1985 victory for The Bone People. The Luminaries was Catton’s second novel.
