What do the conditions mean?

Our conditions mean the following:

  • New - a brand new book
  • Almost New - appears new but is actually secondhand.
  • Very Good - only minor imperfections such as minor scuffs to edge or cover or a price written in pencil or shop sticker.
  • Standard Secondhand - Clearly been read before, but not too bad. We do not recommend these for gifting. Spines usually creased. Could also include creases or folds to cover, some writing such as in the cover or elsewhere, underlining or highlighting, but might not do. Possibly some stains or marks. Similar in general to books in any secondhand shop or charity shop.
  • Poor Condition - Usually this will have a specific problem such as writing inside, water damage, missing dust jacket, heavy staining, large creases or cuts. These are readable copies but not nice ones. On other websites this condition is called 'Acceptable' or 'Fair' , but we want to be more honest.

Number 9 is an enthralling mystery and a study of the intriguing world of numbers at the same time. In solving the riddle, Enjil, a boy mathematician, leads us deeper and deeper into an inner world. Diagrams and picture maps which illustrate the book show how the number nine holds the fate of other numbers, how, like a phantom, it can change and vanish, or like a virus, attack and conquer the character of other numbers. Ultimately nine is seen not just as a number but as a beginning and end, a metaphor for the closed and secretive or the open and inquisitive. Enjil is not just another person, but an animation of our restless spirit, looking for a meaning.
