Is there a HN convention for links to books? This book appears to be available only for preorder now, not yet published. Nobody here has read it, nobody here can read it, and even if they could, this submission will disappear off the front pages before commenters have a chance to order and read the book. Thus the comments section here is going to be useless (or at least more useless than usual).
I don't know what happened to this website but stuff like this keeps hitting the front page more and more often despite having close to zero value. It feels like SEO spam to me.
The person who submitted the link already explained the submission: https://news.ycombinator.com/item?id=46068363
