Publishers can try to predict what books will take off and become blockbusters. They can hope, guess, promote ... but it's the readers who decide.
Children's books have the potential to be hugely successful because they can attract both children and adult audiences. The "Harry Potter" and "Twilight" books fall into that category. So does "The Hunger Games" and its sequels.
They are the superstars of kids literature. So what's next?
