Orlean chronicles the LAPL fire and its aftermath to showcase the larger, crucial role that libraries play in our lives; delves into the evolution of libraries across the country and around the world, from their humble beginnings as a metropolitan charitable initiative to their current status as a cornerstone of national identity; brings each department of the library to vivid life through on-the-ground reporting; studies arson attempts to burn a copy of a book herself; reflects on her own experiences in libraries; and reexamines the case of Harry Peak, the blond-haired actor long suspected of setting fire to the LAPL more than thirty years ago.
