i have a feeling that carlos ruiz zafon didn't wrote the books, i mean he technically wrote it, but when you read the book, you will feel that its really the protagonist who really wrote the book -- zafon is only an organon to convey the story that the character in the story wrote. did i even make sense? no, well it did make sense inside my head, though. i was awed and amazed how carlos ruiz zafon manages to combine the events in the angel's game and shadow of the wind with ease, clarity, consistency and smoothness. i think, the prisoner of heaven, is kind of a bridge that connects the story of its predecessors. the story is very instantaneous, it covers a lot of grounds that answered some questions but also give birth to new questions and mystery, which leads to to the conclusion that there is going to be a fourth book -- this gives me an impression that the first three books is only a glimpse of the entire cemetery of forgotten books universe.
