Skulduggery Pleasant is dead. Valkyrie Cain is cool. Omen Darkly is neither. 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. Some things never change though: bad people still want to do
bad things and Skulduggery Pleasant is still there to stop them. When Skulduggery learns of a
plot to resurrect a terrifying evil he persuades Valkyrie to join him for just twenty-four
hours. But they need someone else on their team someone inconspicuous someone who can go
undercover. Enter Omen Darkly. Student at the new Corrival Academy. Overlooked. Unremarkable in
every way. 24 hours to save the world. One sharply-dressed skeleton. One grief-stricken young
woman. One teenage boy who can't remember which class he's supposed to be in. This cannot end
well...
