60 Years Later: Coming Through the Rye

JD Salinger recently filed a lawsuit againist Fredrik Colting, a young Swedish author, who was publishing a book called 60 Years Later: Coming Through the Rye, which Salinger claims is an unauthorized sequel to The Catcher in the Rye. A judge has ordered to "indefinitely ban the publication in the United States". You can read more at authorsadvocate.net and from the article "Salinger's Last Stand" in Publisher's Weekly. What has intrigued me about this controversy is that Fredrik Colting did not write the book because of his love for The Catcher in the Rye, in fact, he states "I've only read it twice once when I was 15, and once before I started this book. I still have a hard time understanding why it is such a popular novel. To me, it's just some book." Wow I haven't written book (only these insightful and absorbing blog posts) but I would want to be passionate about my subject matter in order to spend all that time writing a book. Interesting--do you find this odd or is it just me?
