The Harry Potter Series
With the recent release of "The Cursed Child", a new play set within the Harry Potter universe, and "Fantastic Beasts And Where To Find Them", a film about a magical zoologist in the series, the world of Harry Potter is being talked about everywhere once again: J.K. Rowling created a true world of magic when she first wrote "The Philosopher's Stone", and today that world spans ever wider.
For those who have never read the series or watched the films: Harry Potter's parents are murdered by a dark wizard when he's a baby, and although he's raised by his Muggle (non-magical) aunt and uncle, at eleven years old he receives an invitation to Hogwarts School of Witchcraft and Wizardry. The initial series of books covers his adventures at Hogwarts, and his eventual defeat of the man who killed his parents: it's a fantasy series, but it's also about growing up, and about the polarizing differences between some people and others.
