Kindle can lose one's place in a book, making it necessary to page through perhaps many hundreds of pages to get back to that point. Perhaps this was an exceptional once only event.  Normally it will automatically go back to the point where one was last reading.  It is also not possible (or at best extremely difficult) to work from different points in a book in random order.  This book is one which is likely to require that facility.  This makes the Kindle unfit for certain purposes.
