How Opal Mehta Got Kissed - a planned YA book about an Indian-American girl who tries to become a more “typical” teen to look more well-rounded for college applications. Got a 6-figure advance (the author had only just graduated college I think) and it was supposed to be a more diverse take on Gossip Girl and other reigning YA fiction of the day. Turns out the whole thing was plagiarised, tons of passages ripped straight from other books in the genre (Princess Diaries etc). All copies were recalled and destroyed! I remember being in middle school when this happened, the author grew up locally to me and it was mentioned quite a bit in teacher lectures about plagiarism.
