The Book That Wouldn’t Burn is a book lover's dream, with a unique metafictional approach that explores the power of the written word. Set in a vast library that transcends time and dimensions, the story follows Elvar, who has been trapped in the library his whole life, and Livera, who flees her settlement after an attack by an enemy. Their paths cross, leading them on a quest for knowledge that leaves readers captivated.

However, this isn't an easy read. It delves into difficult themes such as transience, collective memory, and the dangers of banning books. The story also explores xenophobia and dehumanization, and concepts of time. Just when you think you have it figured out, the book takes you in an entirely different direction.

While the book is a masterpiece, it's not without its faults. The extensive backstory that keeps the mystery alive leaves the reader with a minor connection to Elvar. Additionally, the pacing fluctuates due to a long build-up towards the ending.

Overall, The Book That Wouldn’t Burn is a thought-provoking book that is brilliantly constructed by a genius author. It's a must-read for any book nerd who wants to be challenged.
