Long before there was John Green, Rainbow Rowell, or any other recent chronicler of the teen experience, there was William Shakespeare. In his plays, he tackled young adult angst, love, and lust as it played out in tragic relationships, parental power struggles, and plain old frothy flirtation. So, of course, the Bard’s stories are ripe for reenactment on the pages of YA novels, and these books prove the timelessness of his genius.
