I read City of Ghosts a short while ago. The book only gets better from here! If you are intrigued and want to read my book review, go here https://quillandbooks.com/2019/06/15/city-of-ghosts-book-review/
I’ve not read the sequel, Tunnel of Bones, yet. I hope to get it for Christmas. My current read is Darker Shades of Magic, which is another book by V.E. Schwab. This one is a lot of fun too! So basically I’m a big fan of her!
