Okay, this is a big one.
Big category. Not really a genre (though some have debated it is, I’d argue it’s an age range).
Young adult fiction.
No subgenres in particular.
But I want to know: what do you consider to be the most essential reads for anyone looking to pick up a young adult book? And further, what (for you) makes a young adult book? What is YA?
So, drop to the comments, and discuss. Oh, and list your top three essential YA reads, too!
