There is a lot of books around about rope, about how to, and about what. some are good, some are great, but this upcoming little gem looks much more interesting than most other books. Starting as a kickstarter project, everyone can support it, and get their first edition without waiting on a rainy day outside the bookstore. I know, its not a japanese guy making this one, but if its kmasutra, then it probably should be an indian guy writing this. I am looking forward to November, when it comes available.
