Lauren Weisberger (born March 28, 1977 in Scranton, Pennsylvania) is an American novelist and author of the 2003 bestseller The Devil Wears Prada, a roman à clef of her time as a put-upon assistant to Vogue editor-in-chief Anna Wintour.

In 2003, Weisberger authored her first book, The Devil Wears Prada, which spent six months on the New York Times Best Seller List. The book provides a semi-fictional but highly critical view of the Manhattan elite's empty obsession with materialism and fashion. As of July 2006, The Devil Wears Prada was the best selling mass market softcover book in the nation.

A delightfully dishy novel about the all-time most impossible boss in the history of impossible bosses. Andrea Sachs, a small-town girl fresh out of college, lands the job “a million girls would die for.” Hired as the assistant to Miranda Priestly, the high-profile, fabulously successful editor of Runway magazine, Andrea finds herself in an office that shouts Prada! Armani! Versace! at every turn, a world populated by impossibly thin, heart-wrenchingly stylish women and beautiful men clad in fine-ribbed turtlenecks and tight leather pants that show off their lifelong dedication to the gym. With breathtaking ease, Miranda can turn each and every one of these hip sophisticates into a scared, whimpering child. THE DEVIL WEARS PRADA gives a rich and hilarious new meaning to complaints about “The Boss from Hell.” Narrated in Andrea’s smart, refreshingly disarming voice, it traces a deep, dark, devilish view of life at the top only hinted at in gossip columns and over Cosmopolitans at the trendiest cocktail parties. From sending the latest, not-yet-in-stores Harry Potter to Miranda’s children in Paris by private jet, to locating an unnamed antique store where Miranda had at some point admired a vintage dresser, to serving lattes to Miranda at precisely the piping hot temperature she prefers, Andrea is sorely tested each and every day—and often late into the night with orders barked over the phone. She puts up with it all by keeping her eyes on the prize: a recommendation from Miranda that will get Andrea a top job at any magazine of her choosing. As things escalate from the merely unacceptable to the downright outrageous, however, Andrea begins to realize that the job a million girls would die for may just kill her. And even if she survives, she has to decide whether or not the job is worth the price of her soul.
