HARRY POTTER AND THE PHILOSOPHER'S STONE
Harry Potter lives in the cupboard under the stairs of his awful aunt and uncle, the Dursleys. He receives a letter from Hogwarts School of Witchcraft and Wizardry telling him he is a wizard and inviting him to start school.
Harry learns that his dead parents - who he thought had been killed in a car accident when he was a baby - were killed by evil wizard Lord Voldemort. His father James was a wizard and his mother Lily was a witch. Harry survived with only a scar on his head and he weakened the dark wizard.
Harry catches the Hogwarts Express from platform 9¾, and first meets schoolmates Ron Weasley and Hermione Granger, who are put with him into Gryffindor house.
Harry learns the sport of Quidditch, makes instant enemies of Professor Snape and Draco Malfoy, and learns about the Philosopher's Stone, which is guarded by a three-headed dog.
As Harry races to get to the stone before Voldemort uses it to restore his power, he discovers the dark wizard has taken over the body of Professor Quirrell.
He is helped by the Mirror of Erised, which reflects the onlookers' desire, and Harry is shown the image of his parents.
As Voldemort tries to take the stone to restore him to power he is thwarted by Harry and disappears.

Dementor guards are brought into Hogwarts to protect Harry, but he feels peculiar in their presence.
Traitor Peter Pettigrew, who led Voldemort to Harry's parents' hiding place so they could be killed, is uncovered at Hogwarts. He is the one who really committed the crime for which Black, a schoolfriend of James Potter, was imprisoned.
Harry learns that when his parents were killed, his mother Lily sacrificed herself to save her young son, creating a protection which Voldemort could not break.
Black reveals he is Harry's godfather and has been trying to protect him. Pettigrew escapes before being exposed as a criminal, so Black is forced to go on the run.

HARRY POTTER AND THE ORDER OF THE PHOENIX
With Lord Voldemort risen to physical form once again, a secret society - known as the Order of the Phoenix - has reformed and is keeping an eye on Voldemort's followers. It includes the Weasley family and Harry's godfather, Sirius Black.
Harry goes to a hearing at the Ministry of Magic for a disciplinary hearing about using magic outside school. He is acquitted and allowed to return to school thanks to Professor Dumbledore, who speaks on his behalf.
During his fifth year at Hogwarts School, 15-year-old Harry is in full-blown adolescence, complete with teenage rage, a schoolboy crush and a growing sense of rebellion.

Harry and Hermione discover Hagrid has a giant tied up at his hut. He is Hagrid's brother, Grawp, and he asks them to look after Grawp if something happens to him.
Ron is made keeper of the Gryffindor Quidditch team, but the team's triumph is not enough to take their minds off the looming Ordinary Wizarding Levels (OWL) exams.
Harry has a vision that Sirius is in trouble and goes to the Department of Mysteries, where he thinks he will find him - but it is a trap and the Death Eaters are waiting for them to arrive.
Sirius arrives with Lupin, Moody, Tonks, and Kingsley to save them, but Sirius is killed in the ensuing fight.

Cornelius Fudge is fired as the Minister of Magic as Voldemort and his Death Eaters cause havoc across the UK.

After doing reasonably well in the OWL exams, Harry and Ron sign up for potion classes, and Slughorn lends Harry an old textbook marked as the property of "The Half-Blood Prince".

Harry tells Dumbledore that he suspects Malfoy is a Death Eater.
Dumbledore gives Harry lessons in how to view collected memories from Voldemort's past from the Pensieve.
