Hereticus, the last book of the Eisenhorn trilogy, probably the best story to come out of WH40k so far. It's the story of the Inquisitor Eisenhorn. The book is rich, lavish and vivid in details, and it brings the book to a "reality feel" (and that's hard to do in a fiction). I gave Hereticus 5 stars, since it brings back an amazing story (Xenos style) and has lots of twists, the first half of this book is amazing, and is the best part of the whole trilogy, it has a unique reality feel, it's sad that the Eisenhorn trilogy had to stop here, Dan had finally the perfect balance of story telling, description and style with this book. The book will please anyone from a new fan to a old WH40K expert. It should be noted that a minimum, or basic knowledge of the WH40K universe and the previous books Xenos and Malleus is required for a full appreciation of this book.
