Pendragon: Journal of an Adventure through Time and Space, commonly known as Pendragon, is a series of ten young-adult science fiction and fantasy novels by American author D. J. MacHale, published from 2002 to 2009. The series chronicles the adventures of Bobby Pendragon, an American teenager who discovers that he must travel through time and space to prevent the destruction of the ten "territories": critical times and locations throughout the universe. The series has sold over a million copies. Each book deals with the battle over a particular territory, fought by Bobby's side against the forces of Saint Dane, a shapeshifting demon, who exploits a decisive turning point for the local people of each territory. At this turning point, Saint Dane steps in to guide the territory towards utter chaos, while Bobby and his allies attempt to stop these efforts. The novels use a first-person perspective through Bobby's handwritten journal entries, in which he recounts the events of his adventures to his loyal friends back home, Courtney Chetwynde and Mark Dimond, as well as a third-person narrative to tell the stories of characters other than Bobby—often, Courtney and Mark themselves. Each book of the series repeatedly alternates between these two narrative perspectives. Publication history The first five books in the series, The Merchant of Death (2001), The Lost City of Faar (2001), The Never War (2002), The Reality Bug (2002), and Black Water (2003) were originally published in paperback by Aladdin Paperbacks. In 2004, Black Water made The New York Times weekly nationwide top-ten list in the category "Children's Paperback Books," and a month later, for the first time, the series as a whole ranked in the category of "Children's Best Sellers: Series." The remaining five books, The Rivers of Zadaa (2005), The Quillan Games (2006), The Pilgrims of Rayne (2007), Raven Rise (2008), and The Soldiers of Halla (2009) were all originally published in hardback by Simon & Schuster. As of 2011, all books have been released in both formats. A graphic novelization of The Merchant of Death was also released around the time of the ninth book. The tenth and final novel, The Soldiers of Halla, was released on May 12, 2009. A prequel trilogy created by MacHale but authored by other writers has also been published, collectively called Pendragon: Before the War.
