Unlike the
New Adventures and
Eighth Doctor Adventures which had featured the ongoing adventures of the
Seventh and
Eighth Doctors respectively, and which had been aimed at an adult readership, the
BBC's range of
New Series Adventures are aimed at a younger audience, and also feature very little continuity between the novels, making them very much standalone stories.
The first three hardbacks were released in May 2005 and featured the
Ninth Doctor and
Rose Tyler.
With the unexpected regeneration of Christopher Eccleston at the conclusion of his first season, it quickly became apparent that the book range would also be undergoing a change.
The second and final batch of books to feature the
Ninth Doctor (set later in Season 27 and including
Rose and
Captain Jack Harkness) were released in September 2005.
The first three novels featuring the
Tenth Doctor and
Rose were published in April 2006, while March 2007 saw the release of
Made of Steel, the first book to feature new companion
Martha Jones.
Martha was later phased out and replaced by
Donna Noble for four books in 2008. With the exception of
The Story of Martha, all future books featuring the
Tenth Doctor were to see him travelling on his own.
