Marie Lu is an American young adult author. She is best known for the Legend series. She was born July 11, 1984 in Wuxi China. She's made 22 books and counting. The reason why I think she made the series is based off of China because of all the new and upcoming technology. And telling a story about someone she knew but wasn't a crime she just based off him and if he were bad that would be the stuff he would do.
