Post-9/11 fiction reflects how the September 11, 2001, attacks have influenced our concept of public space, from urban behavior patterns to architecture and urban movement. It also suggests a need for remapping the real and imagined spaces where we live and work. Through close readings of novels from both sides of the Atlantic, this analysis of the literary 21st century metropolis explores the fictional post-9/11 city as a global space not defined or contained by its physical limits.
