What is the best book to sharpen and fully grasp critical thinking skills?

What is the best book, not to learn introductory logic, but to have a balanced understanding of how to think critically and reasonably? I don't want to know how to construct an argument, but how to dissect the argument by finding it's illogical assertions. Sorry, I am having a difficult time describing what it is I am actually looking for. Perhaps I just need to continue to re-read the material I already have until it sinks in. I just feel as if I am not getting the most of this course and it's work and I desire more. i always liked the book ' the little engine that could' it seemed fast paced and it has a great ending~ I guess I read the wrong books because I usually have questions when I am done

hmmmmm i know this sounds corny or what ever but the bible is full of logic and thought processes when you think about it.

I Liked the book " How to think like Einstien" Let me know if this helps. Also play some Soduko. And nintendo ds has some good mind games that might help.
