Firstly, I'm impressed that Victoria Schwab can write across three age categories with equal skill. City of Ghosts is a just-creepy-enough middle grade novel that's perfect to read during October. Schwab successfully maintains her authorial style while adapting both story and prose to suit a younger audience. (Her love of Edinburgh really makes the setting shine, too.)

I gave this four stars because while I found the characters and concept interesting, the plot felt underdeveloped. The villain, in particular, would've benefitted from a bit more detail. Given the word-count limitation that comes with writing MG, I think it's a solid book.

I'm definitely going to read the next Cassidy Blake novel!

(The audiobook narrator was excellent as well - I'm not a good judge of accents, but none of the characters' voices were grating or obnoxious.)
