Resurrection:
A lot has changed. Roarhaven is now a magical city, where sorcerers can live openly. Valkyrie Cain has been out of action for years, recovering from the war against her alter-ego Darquesse, which nearly destroyed her and everyone else.

Midnight:
For years, Valkyrie Cain has struggled to keep her loved ones safe from harm, plunging into battle – time and time again – by Skulduggery Pleasant’s side, and always emerging triumphant. But now the very thing that Valkyrie fights for is in danger, as a ruthless killer snatches her little sister in order to lure Valkyrie into a final confrontation.

Bedlam:
On a desperate journey to recover her sister's lost soul, Valkyrie Cain goes up against the High Sanctuary itself, and there's nothing Skulduggery Pleasant can do to stop her. With Abyssinia's grand plan about to kick off in a night of magic, terror, and bloodshed, it falls to Omen Darkly to save the lives of thousands of innocent people.

Seasons of War:
War is coming. To avert catastrophe, Skulduggery and Valkyrie are sent on a secret mission that takes them away from everything they know, to a forsaken land of magic and grim, unrelenting terror. It is here that Valkyrie will have to fight the hardest ― not only against the enemies who want her dead, but also against her own self-destructive impulses.

Apocalypse Kings World Book Day:
Three ancient gods are freed from their prison with only one desire: to destroy the planet and everyone on it. To save us all, Skulduggery Pleasant and Valkyrie Cain must go undercover in a Dublin school.
