I love Gaiman's prose in general, and I laughed quite a bit reading this -- guy's got a wry, dark sense of humor that really jives with me. That said, this is a 5 stars with an incredible amount of reservations. There's a scene about half way through the book --

Richard's ordeal

-- the metaphor is very well done, and the audio format, especially with the version where Gaiman is reading the book, brings it a kind of immediacy that is...very...emotionally hard to listen to, honestly.

The troll being dangled in front of him, knocked onto the tracks, while Richard pathetically scrambles after it all along -- how sometimes, just surviving in this world is a heroic undertaking and not trivial in the least

-- so much thematically to sink your teeth into here. I've got to adore this book just on the merits of this scene alone; it's incredibly powerful. That said, it's also very triggering re: suicidal ideation, making you doubt your reality, etc. -- especially so if you've ever experienced any kind of housing insecurity. I suggest approaching with caution if that's something you aren't in a good place for.
I'm also really iffy on how the women in this book are written. This is mostly a general vibe I get, but one specific thing that bothered me was that it's a little...troubling how we're given the impression early on Door is like, 14 or 15 or something, but we get occasional incongruous, weird moments where she's sexualized. I get that this is mostly done by bad guys or people with dementia, and I get we're supposed to find it weird. Still. I just get a weird vibe overall, that's all. Not enough fully formed thoughts on this to talk about it; just leaving a note.

I liked this book, but didn't love it. It certainly wasn't my favorite Neil Gaiman book. My favorite was either "Stardust" or "Ocean." To be fair to Mr. Gaiman and the story, however, this is not my normal genre. The story itself was good and very imaginative. I haven't enjoyed villains like Mr. Croup and Mr. Vandemar for a long time! I kept feeling like they'd look like plague doctors with the bird masks. I'm not much into urban fiction, so I could've enjoyed this book more, but the story is very good. I'd read a cookbook if Mr. Gaiman wrote it! I read in a book forum that Neil Gaiman's books are for children. This one definitely was NOT! This is NOT a kid friendly book, people!
