Valkyrie is on a mission. A mission with out Skulduggery. Skulduggery Pleasant is lost in the mysterious land of the Faceless Ones. Valkyrie needs to find him, before its to late....................
The Ithmus Anchor was destroyed, so there's no way to get Skulduggery back. But Valkyrie soon finds out that she can use Skulduggery's real skull instead. He lost his skull, and won a different one playing poker, so now all Valkyrie has to do is find it.
After searching and searching, she comes across a dealer who has his skull. It turns out that the skull was a fake. The dealer sold it to someone with a higher price. After loads more searching, she finds his skull.
She then goes into the portal and sees the faceless ones.
