The Lost Boy was released in November 2008, a full year after the last release of novelisations. It adapts The Lost Boy, the final regular serial of The Sarah Jane Adventures first series. With its release, all episodes of the first season have been adapted. It is the first time a complete season of a Doctor Who-related series had been fully adapted in novelisation form within a year of original broadcast.
Life on Earth can be an adventure, too. You just need to know where to look.
