Query: I liked the first half . . .

I saw a copy of this book at the bookstore, and after flipping through it, ordered it from the public library. Thankfully. I loved the concept, and enjoyed the first few chapters. Once I'd reached the halfway point, however, I began to feel restless, an unusual thing for me when I'm reading. I suddenly realized that I wanted the book to be over. It felt finished, and as if the plot should be wrapping up, but there was still half a book to plow through. If you really want to read this book, I'd recommend saving a few bucks and checking it out of the public library.
