What is Harry Potter

Harry Potter is a series of seven fantasy novels written by British author J. K. Rowling.
The novels chronicle the lives of a young wizard, Harry Potter, and his friends Hermione Granger and Ron Weasley, all of whom are students at Hogwarts School of Witchcraft and Wizardry.
The main story arc concerns Harry's struggle against Lord Voldemort, a dark wizard who intends to become immortal, overthrow the wizard governing body known as the Ministry of Magic and subjugate all wizards and Muggles (non-magical people).

Hogwarts, Hogwarts,
Hoggy Warty Hogwarts.
Teach us something please,
Whether we be old and bald,
Or young with scabby knees,
Our heads could do with filling,
With some interesting stuff,
For now they're bare and full of air,
Dead flies and bits of fluff,
So teach us things worth knowing,
Bring back what we've forgot,
Just do your best, we'll do the rest,
And learn until our brains all rot.

“Whether you come back by page or by the big screen, Hogwarts will always be there to welcome you home.”
