The Seven

The first book in the trilogy was good, the second better, the third the best. Also, book 1 was fantasy, book 2 science-fantasy, book 3 full (mostly military) scifi, with a natural evolution that did not feel out of place.
Well written, with very good characters (mainly the infernals and half-breeds, unfortunately the Seven were annoying and lacked depth), plenty of twists, plots and betrayals, a lot of war and battles, a very good and balanced view of how the Holocaust might have felt like from both sides, some good messages of tolerance, some good humor, a lot of bizarre imagination (in the good sense, as being highly original).
Why not 5/5 then? Most of the book did feel extraordinary, but there are some (large) parts that drag on, and the ending (the last 70-80 pages) is overlong, boring and really unnecessary stretched.
