The Alcatraz series is the only writing of Brandon Sanderson's that I hadn't checked out. I finally remedied that.
Alcatraz vs the Evil Librarians is about a kid named Alcatraz who suddenly finds out he has magic. It's very Young Adult. I like Young Adult books when they're closer to the higher part of the Young Adult age range. Alcatraz is near the lower end.
I felt like this was a book that my kids are almost ready for, not one meant for me. Although I bet I would have loved it if I was 11-13.
I wouldn't recommend this one for adults but if you have kids just hitting the Young Adult reading age this one would be a great book to pick up.
