URL shorteners are generally frowned upon. The book is not notable - no one has written anything about it. And outside of "Show HN", HN is not a marketing platform. At the very least take the time to write a thinly veiled native advertising blog post/review. If you give us original content that contains referers (that directly link amazon instead of sleazy shorteners) people usually do not complain about referers.
