Publishing and film interest
Eric Simonoff, then at Janklow & Nesbit, agented the book. In early 2009, seven different publishing houses vied for the manuscript. It eventually went to Viking Press for an undisclosed amount. According to Publishers Weekly, a reputable industry publication, the final offer was "well into six figures".[dead link]
