This is honestly one of the most bizarre books I have ever read.
It's gripping, no doubt about that. You put it down and find your mind wandering back to the strange lands of the Five Dominions, wondering what will happen next. The strange events, places, and people stick in your mind and invade your thoughts.
While the premise for the book is good, it could have been written better. Too many things are left unexplained, and near the end of the book the characters start acting very out-of-character. Mr. Barker also throws in some pretty graphic and disgusting scenes, seemingly just to shock the reader into going, "Ewwww, gross!"
I enjoyed reading the book once, but I don't think I'll be opening its pages again. In addition to leaving many things unanswered, it could have been about 200-300 pages shorter. But even though I'll never read Imajica again, I think that parts of it will continue to haunt my subconscious for a long time to come...
