WSJ.Com: “Of Copyright & Family Feuds: “Hedge Fund Wives” Goes to Court“:

Tatiana alleges that Natasha surreptitiously copied portions of the book during trips to Tatiana’s New York home. Tatiana also claims that Natasha filed for a joint copyright by allegedly providing the Copyright Office with a version of the book that she’d downloaded from Tatiana’s computer. Then, earlier this month, Natasha allegedly referred to “Hedge Fund Wives” as “our book.” After that she began sending letters to HarperCollins people allegedly threatening to publish the book on the Web if they didn’t respond.
