Tbh It is the best book I have ever read, it was so worth getting at my school library. Yes it was sad but it was just soooo good. Almost all the chapters end on cliff hangers that make u never want to put the book down. But one sad thing is that the story's in the book have happened in real life (like nazi Germany) and it makes u feel sad for the people who had gone through it. You also CANT skip one chapter. But this book is just amazing 👏👏👏👏👏 I personally loved it and will read it again and again
Edit: I also did not know what happened in Syria and Cuba so it got me thinking about that
