Celestial Navigation Book

As much as I appreciate Tom Cunliffe's writing in magazines and books, I did not find this book very useful. It is hard to use when you are actually trying to master celestial navigation without any prior background. In this matter, I think, the organization of the material is of utmost importance, and this book is a bit chaotic in that sense. The matters are somewhat exacerbated by the media of a Kindle book: all the references are skewed, the tables are gone fishing and the drawings are smeared. I may be on a mission impossible trying to learn celestial navigation from a Kindle, but this book definitely didn't fill the bill.
