While this was a very entertaining and enjoyable read the plotline was definitely weaker compared to the first 2 books. The pacing was very fast and didn't allow us to stay in one place long enough to get to know new characters and worlds. I wish we would've seen more of the dragons or the elves. The 2nd book gave us the chance to explore so much of this world, but the 3rd feels a bit like a regress in this regard. It's still worth reading though. We get more information about the dangers that grew in the background and spend a lot of time with characters we know and love (and love to hate?). So if you already read and loved the first 2 books you should definitely pick up this one. You'll have a good time.
What did enjoy were the insights into the library and the new Infos about Alberich. I'm definitely looking forward to seeing more of him.

Again, the plot starts off quite interesting but then it gets really convoluted, with terrible pacing. I wanna read this series but I also hate it 

The Burning Page was an interesting entry in the Invisible Library series. I can't help but wonder what the fallout from the burning page will be and what Alberich meant. As in previous books, Irene's journeys to alternate worlds is more fun than the basic plot line. 

After reading the disaster that was A Discovery of Witches, I was overjoyed to be back in the world of the Invisible Library. It was a comfort to get back to characters I actually cared about! 

This installment of the series brings Alberich back in all of his devious glory (I did miss him). This time, he is targeting the entirety of the Library, aiming to destroy it along with as many Librarians as he can (with a specific focus on destroying Irene). Irene must gather together all her resources and allies, but when push comes to shove, the question of who to trust drives her into a maze of half truths and deceptions.

I definitely enjoyed The Burning Page more than The Masked City. That is not to say I did not enjoy The Masked City. Rather, I felt that this one got back to the main plot. While I enjoy side-quests, I'd rather they not take up an entire book. I'm sure that the events of the second book will become relevant later on in the series. The question of Lady Guantes remains. Anyway, as to this particular installment, I really enjoyed watching the relationship between Irene, Kai, Vale, and Singh. I think that is part of what draws me to this series. The characters are fleshed out, their motivations are known and are at times at odds with one another, and the relationships between them are genuine. There were even times I wondered if Alberich was right in some ways. I am growing more suspicious of the Library as in institution (I would be a terrible Librarian), and I wonder if that's going to come to a head by the end of the series. I'm certain it will.

I am truly excited to get my hands on the fourth book (which will be ready for me in two days!!)

Another fast-paced entry in the Invisible Library series, The Burning Page has the Library under an existential threat. Gates are being destroyed, Librarians are being murdered, and the enemy Alberich is getting close. His plan is to completely destroy the Library, and everything
within - people, books, the entire world of the Library - and there's no good plan to stop him.

Irene Winters, intrepid Librarian; Kai Strongrock, her dragon assistant; and Peregrine Vale, London detective; jump in to do their best to defeat Alberich once and for all. Alas, like the "dead" bodies in horror films, he refuses to stay down. Perhaps this time they'll be able to subdue him, perhaps eradicate him completely. In addition to the threat from Alberich, there are werewolves, flying sleighs, exploding briefcases, and even a power shortage with a brownout.

I really like this series a lot but I felt the last part, the exciting match of wits and powers, was both odd and cliché. Does Alberich have a body or not? Can he be killed or not? Can Irene access the Library if the door is in a fake library with fake books? The big to-do wasn't equal to what came before: the clever plot devolved into banal battle.

That said, I love the characters and I'm about to read the next in the series. I love the idea of valiant Librarians defeating evil and enjoy the plots and characters.
