I read this book for my Multicultural Lit class. I used the Comixology app to read it and it was great. I did sort of miss the paper book experience of the graphic novel. The story is set in Japan and involves 5 friends and a new kid in school. The main character receives a letter from herself, 10 years in the future. The letter warns her that she has to do something to prevent a terrible event. It tells her what happened and what she should do differently. At first, she doesn't believe it, but as events in the letter start happening, she realizes it is the truth.
This story involves typical teen issues, including love, dating, jealousy, insecurity, etc. The action mostly takes place in the present with intermittent flashforwards to 10 years in the future.
I enjoyed the book, but I don't know if I will read the sequels (there are at least 5). I needed to read a manga for my class, and the letters from the future appealed to me. It was a fun story, but I usually prefer horror, sci-fi, or fantasy.
