Today Scholastic unveiled the new cover for the US paperback edition of Harry Potter and the Prisoner of Azkaban, to be released this August.
The cover, seen above, depicts the scene in which Harry casts a Patronus on the Black Lake to protect himself and Sirius. It is a more simple design and illustration than the other two covers, which can be viewed here (book one) and here (book two). All three covers have been designed and illustrated by artist Kazu Kibuishi.
With the release of this cover we have four more to go, and they will be unveiled throughout the summer. The covers will be part of a re-release of the US paperback editions of the books, and will be available on August 27.
