Falls Church may soon be known as the “Harry-est” town in America.

Amazon.com is running a promotion in honor of the final installment of the “Harry Potter” book series. The town that pre-orders the most copies of the book will win $5,000 for the local charity of its choice. Falls Church isn’t the only local contender; Fairfax is ranked third and Vienna fourth. Herndon (28), Rockville (59) and Alexandria (75) are also on the list.
