Lauren Kate is an internationally bestselling author of young adult fiction. Her books have been translated into over thirty languages and include The Betrayal of Natalie Hargrove and Fallen , which reached number 3 on the New York Times Best Seller List for children's chapter books on January 8, 2010, remaining there throughout April 2011. Fallen's sequel Torment entered the NYT Best Seller List at number 1. 
Kate was raised in Dallas, Texas, and has a master's degree in fiction from the University of California, Davis. Kate has stated that experience of the " Old South " in the Atlanta area (she went to college at Emory) inspired her to set Fallen in a Civil War era academy. 
Kate has stated that her high school did not provide the basis for Sword and Cross in the Fallen series. In fact, she based the high school setting of The Betrayal of Natalie Hargrove on the Dallas high school she attended (Plano senior High School).
The Fallen series employs Kate's many months of theological research. She had gotten the idea for the series from a line in Genesis that she came across whilst studying the Bible in graduate school in California.
Kate married Jason Morphew, a singer-songwriter, in 2009. They have a daughter, named Matilda (born February 2013)  and a son, named Venice (born June 2014).  The family currently lives in Laurel Canyon, Los Angeles.
Her standalone novel, The Betrayal of Natalie Hargrove, was released on November 12, 2009, with her second work, Fallen—the first in the Fallen series—also released that year. Torment , the sequel to Fallen , was released on 28 September 2010. It debuted at number 1 on the New York Times Bestseller List ( Fallen came in that week at number 2), remaining at that position through the week of October 17. The paperback edition of Fallen debuted at number 1 on the list, as well. The third book in the Fallen series, entitled Passion , was released on June 14, 2011. A new edition of Natalie Hargrove was also released on the same day as the paperback edition of Torment . On June 23, Passion reached number 7 on the USA Today Bestseller List, for books overall. On July 3, 2011, Passion qualified the Fallen books for the Series section of the New York Times Bestseller List; it entered the list at number 2, behind the Hunger Games books. Each of the aforementioned books has appeared atop many other countries' bestseller lists, as well.
