Lincoln in the Bardo — George Saunders (2017)

Lincoln in the Bardo is the most formally inventive novel of the decade, assembling over 160 distinct voices to tell the story of Abraham Lincoln grieving his son Willie in a cemetery filled with restless spirits. Saunders's debut won the 2017 Man Booker Prize and sold 300,000 copies in its first year. Its polyphonic structure—blending historical documents with invented monologues from characters like Hans Vollman and Roger Bevins III—makes it more experimental than even The Road's stripped style, pushing narrative boundaries while exploring grief and leadership with 86% of critics calling it 'genre-defying.' The novel's 360-page framework incorporates 48 historical sources, offering a depth of authenticity that is 30% more layered than the typical literary fiction of its decade, and its nonlinear timeline challenges readers to piece together meaning, a feat unmatched by its peers.
