This was such an improvement over book 5 it's unreal- plot was super concise, learning about what the Passage actually is was so good and I adore Melancolia as a villain. Loved the Lord Vile twist and the fight between him and Darquesse? Incredible. Thank fuck that stupif plotline with Caelan is over, and I like that Valkyrie was able to admit that she'd been an idiot in regards to Fletcher. Seeing her turn into Skulduggery more and more every book makes my teeth hurt. And them finally knowing what China did? Especially now because Valkyrie doesn't have Tanith? Ouch.
