Harry Potter And the Prisoner of Azkaban continues on the plot revealed in the two other previous books. However the book is some what detached from the other two and I fail to find a direct continuation of the plot into the third book. It seems as if the book is seperated from the other two as it does not focus directly on Voldemort instead on Sirius and wormtail. I feel that the plot is lost somewhere along the story and suddenly u-turns into a dramatic series of events begging with siriuss real identity. The book fails to live upto the high standards of the other harry potter books and is a failure (somewhat).
