Mortal Coil

The blonde girl with the black lips turned to Valkyrie. 'We know,' she said. 'We've seen the future. We know you're going to kill the world...'

Skulduggery Pleasant is back, and reunited with his original head. But all is not well in the magical world. For one thing, there's an unstoppable assassin with a face-mask on the loose... and for another thing, Valkyrie has discovered she might be Darquesse, the evil sorceress set to destroy the entire world. The problem is, she doesn't feel she can tell Skulduggery what she's learned, and so she must try to change her terrible destiny alone.

But the price of a new fate is high, and if she fails, she'll die alone too.

With Valkyrie on her own quest, Skulduggery and the gang are even more vulnerable. Which is a shame, because remember that remnant the Necromancers had? They've still got it - and they're thinking about letting it out...
