The Maleficent Seven (2013) (7–8) A
spin-off novel featuring Tanith Low taking place between the seventh and eighth books was released on 28 March 2013 in the U.K & Ireland and 1 April in other countries. The cover and title (
Tanith Low in... The Maleficent Seven: From the World of Skulduggery Pleasant) were released on 7 December 2012 after several delays, with Landy stating it to be his favourite book cover ever. This time, the bad guys take the stage. Tanith Low, now possessed by a remnant, recruits a gang of villains – many of whom will be familiar from previous Skulduggery adventures – in order to track down and steal the four God-Killer level weapons that could hurt Darquesse when she eventually emerges. Also on the trail of the weapons is a secret group of Sanctuary sorcerers, and doing his best to keep up and keep Tanith alive is one Mister Ghastly Bespoke. When the villains around her are lying and scheming and plotting, Tanith needs to stay two steps ahead of her teammates and her enemies. After all, she's got her own double-crosses to plan – and she's a villain herself... It is a good day to be a bad guy.
