I feel like Maureen achieved with this book what was lacking in the Madness Underneath - a single, driving, cohesive plot that carried through the book. I feel like some revelations were rushed too quickly and I wish the end hadn't resolved itself so simply, and I did find it sliiiightly irritating that Freddie was a genius in absolutely everything relevant to the plot, BUT: 
 All those things don't really matter because this book was so FUN. Rory is such a smartarse ("I stopped by my bedroom door. This was the only one that was closed. If this was my subconscious talking, it was kind of a dick.") and there's lots of kickass and creepy ghosties. There's a queer character! Sure, she's only a side character, but Maureen Johnson proved just how easy it is to increase queer representation in books: you see that bit where you've got 'he', as the character refers to their ex? Just replace it with 'she'! DONE. It feels quite a lot darker than the previous books, or at least in a different way, but I was super into it. I did the bad thing and when I was about 1/2 way through skimmed the rest of the book to see if I could pick up any information about a key plot point and when I saw something that gave it away (god it's hard to say this without spoiling) I had an intense excitement-squirming reaction to it, which I think is a good sign, right? 
 The main thing to me is that I stayed up until 1am two nights in a row to finish this book, and seeing as I haven't been able to concentrate on anything else for longer than 5 minutes in the past two weeks, I count that as a win for this book. 
 Can't wait to read the last book in the series (I'm pretty sure it's a four book series???) and wallow in some more sweet, cheesy, ghost-butt-kicking YA.
