thanks to @jamalexa for monthly updates. This is my review of this product : gives 3+ KDP interiors for trending topics you can use as a base for a book.
Good quaity and in multiple formats (pdf and ppt for example) the actual monthly newletter is interesting, formatted well and some interesting case studies or a deeper dive into best sellers inc keywords.
Overall a worthwhile newsletter if KDP is your thing and you don't have current access to some of the tools like bookbolt.
