Although this is billed as a second book, it's really just the second half of what should have been one book. I find that irksome. A book should tell a whole story, in my opinion.
Also, it's really weird that the prequel, first book, and second book all have the same title, just with #0, #1, and #2 after it. Was it really that hard to come up with discrete titles, or even subtitles that would differentiate the books?
