J.K. Rowling is in court trying to kill the publication of Harry Potter Lexicon, an unauthorized encyclopedia devoted to the fantasy world she created, US reports

J.K. Rowling "I really don't want to cry,"

"I really don't want to cry," said the British-born author, 42.

Rowling also reportedly denied the case was about money and said she considered the prospective volume by author Steve Vander Ark, a librarian, and his publisher, RDR Books, in Muskegon, Mich., "an act of betrayal."

Rowling filed suit earlier this year, claiming that the book is "nothing more than a rearrangement of her own material."
