Emily Dickinson's definition of poetry comes to mind, “If I read a book and it makes my whole body so cold no fire can ever warm me, I know that is poetry. If I feel physically as if the top of my head were taken off, I know that is poetry. These are the only ways I know it. Is there any other way?”
In less eloquent terms, I know I'm reading a good book when I slow way
down, start to receive the words with reverence, and begin to grieve when the book is nearly done. I'm not sure why this book is viewed as young adult literature - the story of Liesel and Death (who is the narrator) could appeal to anyone.
Read it slowly.
