Oliver, a young and lonely american in paris, is sloggin through a dreary winter and a rigorous school. His father is very busy and his mother thinks he's still three years old. His only friend, Neige, had a disagreement with him and they haven't spoken for months.
Then, on the night of Epiphany, he puts on a paper crown, stands in the window and tell himself, ironically, that he is king of the window. This is the end of normal life, and the beginning of an adventure that will, in one short week, span more than the universe, include lost souls, window wraiths, an old lady with disdain for most people, particularly Americans, feather swords, bubble wands, and the Eiffel tower--all in ways you never could imagine.
this book, although it has very simple explanations throughout, as if one were explaining meanings to a child, is also very thought-provoking and requires some serious intellectual ability. and it has some serious action! replete with a high-speed chase across the multiverse, snow in Paris, and an almost quantum computer, this is not a book of fluff and nonsense. at least, not in the way one might think. This takes a strong reader armed with a high level of credulity, and a sense of wonder.
