Playing With Fire is the sequel to Landy's first novel, Skulduggery Pleasant. And Skulduggery and Valkyrie, aka Stephanie, are back in another action-packed adventure. Learning how to use her powers, Valkyrie, now 13, has the added stress of school and appearing normal to her family and friends on the outside. She and Skulduggery chase after bad guys at night, but often during the day as well.
Meanwhile, Baron Vengeous has escaped from his prison, bent on bringing the Faceless Ones back to life. The Baron has only been captured once before, and it was by Skulduggery. Once again, Skulduggery is called in to recapture the Baron and bring him to justice, Valkyrie at his side. But things seem to go wrong from the very beginning. Valkyrie is one of the Baron's main targets, and he sets a vampire and other beings out to capture her. It also appears someone very high on the "good" side is leaking information to the Baron. Will they be able to save the day?
Written with the same humor as the first book, Landy has created yet another exciting adventure.
