good book kind of sad at the end

I was reading this book nonstop and had a hard time putting it down it got really sad near the end but I felt like it was fitting

This is a book about a boy who has a friend that has a brain tumor and is struggling to stay alive. the boy is very sad because his friend is in the hospital. read this book to find out if his friend survives

I think it’s a basic story about a boy going through stuff

I thought it was an awesome book but the ending was sad still I recommend it.
