With about one million new books released each year, writing has become a very popular profession. Novelists, experts in numerous fields, and even celebrities are behind some of the most popular books on the market today. But many of the so-called authors didn’t actually write their own books. Ghostwriters step in when a person who wants to write a book lacks the time or the knowledge to get the job done. Part of the They Do That for a Living? series, Ghostwriters explores this unusual career and some of the most popular ghostwritten books that have made their way onto best sellers lists in recent decades.
