NEW YORK (AP) — J.K. Rowling added a subtle comment under her pen name Robert Galbraith on Wednesday about the standoff between her publisher and Amazon.com.

The “Harry Potter” author noted in a tweet from @rgalbraith that there are “lots of ways to order” her novel “The Silkworm” in the U.S., as “Amazon kindly suggest(s).” Rowling spokeswoman Rebecca Salt confirmed that the twitter account was authentic.
