Query: This one's a definite keeper.

I've recently finished the book, and I must say, this book is very well done. I enjoyed it thoroughly.Part of the reason as to why I enjoyed it so much was that the tone of it was real. Now, those of you that have read this book or part of it have probably taken notice of the typographical errors in the book. Personally, I saw this as making the book better in that it it personalized the book a bit more. The first person voice wasn't entirely perfect, as no one's is (unless you're really bland). It gave the book a bit more of a human quality.All in all, I definitely recommend reading this book. It's very worthwhile. Kudos to Mr. Truong!
