Mark T. Sullivan (b. 1958) is an author of thrillers. Born in a Boston suburb, he joined the Peace Corp after college, traveling to West Africa to live with a tribe of Saharan nomads. Upon returning to the United States, he took a job at Reuters, beginning a decade-long career in journalism that would eventually lead to a job as an investigative reporter for the San Diego Tribune. Sullivan spent the winter of 1990 living with a group of skiers in Utah and Wyoming, and used the experience as the foundation for his first novel, The Fall Line (1994). In 1995 he published Hard News, a thriller based on his work as a reporter, and a year later he released The Purification Ceremony, which won the WH Smith Award for Best New Talent. His most recent work is Private Games (2012), which he co-authored with James Patterson. Sullivan lives with his family in Montana, where he skis, hunts, and practices martial arts.
