I picked up an advance reader's copy of this at the BEA.
Barbara applies the same method she used in Nickel and Dimed to examine the working-class life to examine the life of a middle-class job seeker. She sets herself up with a good resume, references, etc. and sets off to look for a job in PR. She meets a lot of job-seekers - and doesn't find a job.
This book will be released in September.
