Plenty of critics have lamented the rise of Young Adult literature, but its popularity isn’t accidental. The genre is focusing on contemporary problems and, more importantly, manifesting them in easily digestible ways that appeal not just to teens, but to adults as well. Damien Walter explains at the Guardian:
Young adult novels externalise evil as an enemy that can be seen and understood. They give teenagers a Lord Voldemort, a monster that can be defeated, an evil that can be vanquished. But increasingly the evil in young adult fiction is the adult world itself.
