"Young-adult fantasy is in the main, written for, published for, or marketed to readers between the ages of 12 and 18. For the purposes of this page we have decided to feature books that we believe are both aimed at the YA market and also feature a young adult as the main character. And so therefore coming-of-age also plays a large part in the books we have chosen. Many of the books will be familiar but we hope there are also a few surprises that allow you to discover some great new titles."
This is an excellent place to start if you want to get a grasp of the genre. I like the overlap with adult titles and the combination of classic and new.
