The Palace of Glass is the third book in The Forbidden Library series.
Once again Alice is on an adventure this time to get revenge for the death of her father. With Ending as a guide Alice ventures into a book to find a portal to a Palace of Glass that houses a prison book. Determined to find a way to trap Geryon for having been part of her father's demise Alice is willing to do anything no matter the cost.
I had to remind myself a few times that this is a story geared towards middle school students. Some parts seems a bit too convenient for Alice and things happened too easily. Despite those flaws I did enjoy the story and the execution of how Alice thinks. She is a tween still and while she wants revenge it is not in her to physically hard someone. Despite some pacing issues and less action overall I still enjoyed The Palace of Glass and cannot wait to read The Fall of the Readers.
