There are a great many things wrong with this book, starting with the cover art: it has a flying saucer zapping a sailing ship with a death ray, something that - thankfully - doesn't happen in the book. Then there's the length: over a thousand pages, making it thicker and heavier than my copy of the bible, although admittedly the typeface is larger. And it is at least a better story than the bible, making use of such advanced techniques as causes preceding effects, characters having believable motivations etc. Trouble is, it's still not that good. Much of that length is taken up by lengthy internal monologues which serve to set the scene but which digress to such an extent that, when they occur in the middle of a conversation (as they almost invariably do) it's hard to keep track and is terribly jarring when a character finally decides to say something. And there's nothing exciting and new at all when compared to the earlier books in the series. It's merely a small development of themes that we're already very familiar with from the first three volumes. Add to that a cast of so many characters that the appendix listing them all covers 32 pages, and that they all have idiotic names which are based on normal names but with all the vowels hideously butchered, and it's too easy to lose track of what's going on.
I quite enjoyed reading it, but it's dreadfully flawed.
