Quicksilver

If you get through the first 200 pages, the book pays off, but it still is a struggle at times: a bit too much details and characters at times. But, it's as important to stress that there are as much brilliant parts as well.

Also, if you aren't that interested in Daniel at first: hang on, because in the second part and third part of this book he only plays a minor role, and two other, much more interesting characters are introduced.

All and all, very much worth the effort. My hunch is that the next book in the cycle will even be better.
