Luke is scared about going to university...but something much more terrifying is threatening his very existence! A creepy Nightmare Man haunts his dreams and begins to take over his waking life, too — but he can't tell anyone. Will Sarah Jane and his friends figure out what's happening and make sure Luke doesn't disappear forever?
This is the first Sarah Jane Adventures novelisation to be released in e-book format only. It was initially announced as a print release, but later cancelled on 18 September 2010 in favour of e-book alongside the novelisation of Death of the Doctor. It was released for download in the United States and the United Kingdom on the Kindle on the 25 November2010. It was also released for for the Kobo reader in Adobe DRM EPUB format in November 2010.
This is the first Sarah Jane Adventures novelisation to feature the Doctor Who logo used from 2010-present.
Luke is stated to have just finished the diet that he was on in the novelisation of The Wedding of Sarah Jane Smith and packs three pairs of trousers that have stretchy waistbands to accommodate for the freshman fifteen, which he is anxious of gaining.
The story retains a line of dialogue originally written for the TV version but cut from broadcast that hints that Luke may be gay; the implication of this line was confirmed by Russell T Davies in a 2013 interview in which he revealed CBBC had asked for a gay character to be included in the series, and Davies decided to establish Luke as such. However, due to Elisabeth Sladen's unexpected death, the storyline (and the series) wasn't expanded.
As noted above, the novelisation includes appearances by the Brigadier, Martha Jones and Mickey Smith, who do not appear in the televised version of the story.
