I’ve been trying to remember the title of for ages. I read it in middle school so somewhere around the early 2010s. It was a book about this teenage girl spy who has to go undercover as a princess. In one of the books, she meets the prince and they kind of start to fall in love. I remember two of the covers. One was baby pink with a pearl bracelet on it and one was baby blue with a compact mirror on it. (The colors of the covers may be switched). I’ve been trying to find this book for ages but every time I type it into Google, it shows The Princess Diaries by Meg Cabot and I know for a fact that that’s not it, I’ve never read The Princess Diaries.
