So a year or two ago I started reading the first book and didn't like it but now that quarantine has started I read up to date and I absolutely love it and can't wait till the anime. I suggest this for ages 10 and up. This book is absolutely fantastic! I love it a lot because it has so many cool characters and the art looked the best I've seen. You should read the life novel it is an absolute game-changer. It started off slow but you'll like it once you get caught up. Personally, I think it's the best book I've ever read and it has insane plot twists.
