Query: Writers experiment

It's always interesting when the subject matter, plot and characters are the same but the writers change mid-story. The first book by Dan Abnett had superior plot development and interesting dialogue. Moving to the second book the plot dissolved into a Zombie novel with little to no creativity in the battle scenes. The dialogue sounds like it was written in a middle school creative writing class. I'll move to the third book more hopeful.
