Now he has escaped, leaving only two clues as to where he might be headed: Harry Potter’s defeat of You-Know-Who was Black’s downfall as well. And the Azkaban guards heard Black muttering in his sleep, “He’s at Hogwarts… he’s at Hogwarts.”

Harry Potter isn’t safe, not even within the walls of his magical school, surrounded by his friends. Because on top of it all, there may be a traitor in their midst.

“Isn't it reassuring that some things just get better and better? Harry is back and in fine form in the third installment of his adventures at Hogwarts School of Witchcraft and Wizardry. . . . Myriad subplots . . . all mesh to create a stunning climax. The pace is nonstop, with thrilling games of Quidditch, terrifying Omens of Death, some skillful time travel, and lots of slimy Slytherins sneaking about causing trouble. This is a fabulously entertaining read that will have Harry Potter fans cheering for more.” – School Library Journal, starred review

“The Potter spell is holding strong.” – Publishers’ Weekly, starred review

“The Harry Potter epic continues to gather speed as Harry enters his third year at the Hogwarts School for Witchcraft and Wizardry and does battle with the traitor behind his parents' deaths. The main characters and the continuing story both come along so smartly (and Harry at last shows a glimmer of interest in the opposite sex, a sure sign that the tides of adolescence are lapping at his toes) that the book seems shorter than its page count: have readers clear their calendars.” – Kirkus Reviews

“In many ways the best yet” – Voice of Youth Advocates
