Query: Simplistic writing, and an unfortunate author.

The introduction to Japan and the Tokugawa Era provided in this book was good, but I thought the plot and character development was simple. I wouldn't have minded this and would've still rated it an okay book except that upon posting a relatively benign review of it on Goodreads, the author himself verbally snarked back at me. A few of my students posted and he insulted them as well! I couldn't believe it.Suffice it to say I'm even less impressed with his work now, and certainly wouldn't recommend anyone purchasing his novels. I can't wait to introduce my students next year to a better representation of Japan (during the Heian Period): excerpts from The Pillow Book of Sei Shonagon, an amazing historical artifact. So long, "Demon."
