The Library of the Unwritten does a fantastic job at merging the devilish elements of hell and fallen angels with the timeless allure of libraries. The characters who populate this sojourn into the many realms of belief are equal parts bookish and demonic - yet not without their redeeming qualities (Claire, and Hero are particular favourites).
Whilst I'm touching upon characters, I need to make mention of how diverse and unique each one is. Claire, Hell's librarian is vibrant, tough, and not without her darker moments, whilst Brevity, the head librarians muse, is a perfect ying to Claire's yang. Then there's the damsels, Hero and Brit; characters who exist only in the minds of their authors until the unfinished manuscripts hit the stacks in Hell's library - these characters are cleverly crafted and critical to the core plot. You've also got the stock standard demons and angels too stuck in eternal conflict, which I won't go into detail as to avoid spoilers, needless to say, there's a lot going on in this book and each character is given their time spotlight.
The Library of the Unwritten reads like a fantasy adventure book complete with a meaningful quest for a loyal band of heroes and plenty of dangers and pitfalls in their way. Ultimately the mantle of each character is put the test with some passing and others making the reader form completely different opinions of them from when the book started out. As you can gather, this story is heavy on character growth and development with the story happening around them (don't get me wrong, the story is a pretty good one).
Overall, I really enjoyed The Library of the Unwritten and can't wait to see what's next for these characters.
