More plagiarism charges have been made against Kaavya Viswanathan’s “How Opal Mehta Got Kissed, Got Wild, and Got a Life.” At least three passages “bear striking similarities to writing in ‘Can You Keep a Secret?,’ a chick-lit novel by Sophie Kinsella. The copying from Ms. Kinsella’s book does not seem to be as extensive as Ms. Viswanathan’s borrowing from two novels by Megan McCafferty, ‘Sloppy Firsts’ and ‘Second Helpings,’ both published by Crown, a division of Random House. In that case, Crown contends that more than 40 passages were copied from Ms. McCafferty’s books.”
