Harry Potter hasn’t lost a bit of his magic.

The sixth book about the boy wizard, “Harry Potter and the Half-Blood Prince,” has sold more than 11 million copies since its U.S. release July 16, publisher Scholastic Corp. says.

The book also is selling at a faster pace than its predecessors. The fifth installment, “Harry Potter and the Order of the Phoenix,” took an additional three weeks to achieve the same sales total.

“The pace is definitely faster. … This is the most successful Harry Potter,” spokeswoman Kyle Good said.
