The book "Java Spider", is a "like it or hate it" book. Personally i did not like it much because the story progressed very slowly and it didn't catch my attention. the book is VERY direct and filled to the brim with easily forgettable details that, most of the time, are EXTREMELY unnecessary. For example, there was a taxi scene featuring one of the characters. It was 6 pages long, and easily forgettable. But with every detail in the book, it gives a very vivid image in your head like watching a movie. Because of this, this is not a deep novel so don't expect any hidden stories to be woven throughout the book.
The book isn't really bad, but is just one of those "film-to-book" type of books that don't really give the reader much involvement within the story's progression.
