The premise is a clever one and I mostly enjoyed the story, but I found that the intrusive narrator kept getting more and more annoying. I just wanted him to shut up, go away, and let the story tell itself. The ending also left me a tad perturbed. There will apparently be more Alcatraz adventures. I will probably read them, since I do enjoy the premise, but the narrator had better take a bit of a vacation or I may become one of the evil Librarians who want to rid the world of Alcatraz once and for all. (BwaaaaaHaaaaaHaaaaaHaaaaaHaaa!)
