Vowell tackles subjects such as identity, politics, religion, art, and history with a biting humor. She searches the streets of Hoboken for traces of the town's favorite son, Frank Sinatra. She goes under cover of heavy makeup in an investigation of goth culture, blasts cannonballs into a hillside on a father-daughter outing, and maps her family's haunted history on a road trip down the Trail of Tears. Vowell has an irresistible voice—caustic and sympathetic, insightful and double-edged—that has attracted a loyal following for her magazine writing and radio monologues on This American Life.
