Indecision

As you all know, I haven't been reading books for the past few days. This is due to the fact that I don't really understand "Schild's Ladder".

I have two books that I would like to read, but I'm am caught in a pickle. I do not really know which book I want to read first. This is where you, my followers, come in. I will post a poll up where you can vote on one of the two books. I had thought about this and figured that not many people would know anything about these books, so I will post what is in the dust-covers and let you know what they are about.
