I own every book (except for the short stories, excluding Rath and storm) and apocalypse was a little worse than the otherse in the series. Personally, invasion was the best, and apocalypse the weakest. However it did finish the long story arc, so I finished in 3 hours
Same as with ademis, I read it straight through because I was so desperate to know what happens to everyone. It was good reading, but I wasn't really paying attention to style or anything, only the plot itself (which took many cool twists that I for one would not have guessed)
One question: If dwarves have been alive all this time and everyone knows them and apparently there are people (Eladamri) who know their language, where the heck have all the dwarf cards been????
