Anne Dayton is one of the famous British children's literature writers. What makes her unique is that she can contain profound life truths in simple stories, which makes people feel crystal clear after reading them. For this reason, her books have won the highest awards in children's literature, such as Carnegie Prize and Nottingham Prize for Literature. This series of "Angel Yuanji" is the pinnacle of her "Crystal Novel". As soon as it came out, it swept the entire European and American campuses. The first book in this series, Wings of Angels, has been bought out by Disney, and the image of Melanie, the protagonist in the original book, has also been registered as a trademark of casual wear, sunglasses and other products, becoming a symbol of fashion.
