Written in 1917, Milne's introduction begins "This is an odd book". Ostensibly a typical fairytale, it tells the story of the war between the kingdoms of Euralia and Barodia and the political shenanigans which take place in Euralia in the king's absence, all supposedly rewritten by Milne from the writings of the fictional historian "Roger Scurvilegs".

Milne created the story to contain believable, three-dimensional characters, rather than the stereotypes which will satisfy children. Hence the book introduces us to a princess who is far from helpless; a prince who, whilst handsome, is also pompous and vain; an enchantment which is almost entirely humorous; a villain who is not entirely villainous and receives no real comeuppance; a good king who is not always good; an evil king who is not always evil, and so on. The result is a book which children may not enjoy as much as adults.

The book was written by Milne partly for his wife, upon whom the character of the Countess Belvane was partially based. (wikipedia.org)
