If you are ever in a position of having to teach pre-service teachers about young adult lit, this is your book.
If you are ever in a position of having to explain YAL to people, this is your book.
If you've never read YAL and want recommendations based on genre, topic, and/or themes, this is your book.
If you're a middle or high school English teacher looking for strategies, this is your book.
If you're a librarian looking for titles, reader advisory, book lists, recommendations based on genre, topic, theme, etc., this is your book.
For everyone else, skip. It's not overly scholarly, which may be a plus to some readers. It's easily broken down and written by many people, so a lot of perspectives are covered. But many--too many, really, references are for white and/or male writers, even when not discussing YAL. It's not clear who the audience is for this--teachers? librarians? scholars?
The layout is also confusing. Too many confusing inserts make the flow difficult. And, I've pointed out other errors that were missed in editing this book. Overall, this was frustratingly not what I wanted or hoped for, nor does it add to the field in a new or exciting way.
