This quote is about judging books for young adults. The quote suggests that when reading books meant for a young adult audience, the reader should be able to tell if a book is worth their time in just four pages. The author suggests that the best way to do this is to look for the early establishment of conflict, and look for themes of hope, family, friendship and overcoming hardship. If these elements are present in the book, it is usually worth the reader’s time. Otherwise, the reader should not spend any more time with it.
