Alcatraz Versus the Evil Librarians (Alcatraz #1) by Brandon Sanderson
I thought a lot of the intro scenes were somewhat needless although that might not have been the case if I had been reading it in book form rather than listening to the audiobook version (since I read a bit faster).
Granted, this is probably at a younger age level than I am suited for reading and would have earned a higher rating if I was younger. Nonetheless, I did like a lot of the weird twisted logic, and hats off to Sanderson for the absurdity level. Sanderson's world-building powers are still on display in this book with very well though-out "curses" that are actually great abilities which are revered in a different world. (If you can't tell, I love Sanderson's world-building/magic systems)
I like that this somehow manages to talk about librarians as "Big Brother" in a fantasy setting and makes swords more powerful than guns.
This is a good read for those who want a bit of lightheartedness and don't mind that this is written for kids.
