  the most evil and powerful dark wizard in history, lord voldemort, murdered married couple james and lily potter but mysteriously disappeared after failing to kill their infant son, harry. while the wizarding world celebrates voldemort’s apparent downfall, professor dumbledore, professor mcgonagall and half-giant rubeus hagrid place the one-year-old orphan in the care of his surly and cold muggle uncle and aunt, vernon and petunia dursley, with their spoiled and bullying son, dudley. ten years later while living at number four privet drive, harry is tormented by the dursleys, treated more like a servant than a member of the family and forced to live in a cupboard under the stairs. shortly before his eleventh birthday, a series of letters addressed to harry arrive, but vernon destroys them before harry can read them, leading only to an influx of more letters. to evade the pursuit of the letters, vernon first takes the family to a hotel, and, when the letters arrive there too, he hires a boat out to a small island. on harry’s eleventh birthday at midnight, hagrid bursts through the door to deliver harry’s letter and tells him what the dursleys have kept from him: harry is a wizard and has been accepted into hogwarts school of witchcraft and wizardry. hagrid takes harry to a hidden london street called diagon alley, where he is startled to discover how famous he is among the witches and wizards, who refer to him as «the boy who lived.» he also finds that his parents’ inheritance is waiting for him at gringotts wizarding bank. guided by hagrid, he buys the equipment he will need for his first year at hogwarts and receives a pet owl. a month later, harry leaves the dursleys’ home to catch the hogwarts express from king’s cross railway station. there he meets the weasley family, who show him how to pass through the magic wall to platform 9¾, where the train that will take them to hogwarts is waiting. while on the train, harry meets two fellow first years, ron weasley, who immediately becomes his friend, and hermione granger, with whom the ice is a bit slower to break. harry also makes an enemy of yet another first-year, draco malfoy. draco offers to advise harry, but harry dislikes draco for his arrogance and prejudice and rejects his offer of «friendship». at hogwarts, the first-years are assigned by the magical sorting hat to houses that best suites their personality. while harry is being sorted, the hat suggests that he be placed into slytherin which is known to house potential dark witches and wizards, but when harry objects, the hat sends him to gryffindor. ron and hermione are also sorted into gryffindor. draco is sorted into slytherin, like his whole family before him. harry starts classes at hogwarts school, with lessons including transfiguration with head of gryffindor, minerva mcgonagall, herbology with head of hufflepuff, pomona sprout, charms with head of ravenclaw filius flitwick, and defence against the dark arts with quirinus quirrell. harry’s least favourite class is potions, taught by severus snape, the vindictive head of slytherin who seems to loathe harry. harry, ron, and hermione become far more interested by extracurricular matters within and outside of the school, particularly after they discover that a huge three-headed dog is standing guard over a trapdoor in a condemned corridor. they also become suspicious of snape’s behaviour and become convinced that he is looking for ways to get past the trapdoor. harry discovers an innate talent for flying on broomsticks and is appointed as seeker on his house’s quidditch team, a wizards’s sport played in the air. his first game goes well until his broomstick wobbles in mid-air and almost throws him off. ron and hermione suspect foul play from snape, whom they saw behaving oddly. for christmas, harry receives an invisibility cloak from an anonymous source and begins exploring the school at night and investigating the hidden object further. he discovers the mirror of erised, in which the viewer’s sees his deepest desires becoming true. thanks to an indiscretion from hagrid, harry and his friends work out that the object kept at the school is a philosopher’s stone, made by an old friend of dumbledore named nicolas flamel. harry is also informed by a centaur he meets in the forest that a plot to steal the philosopher’s stone is being orchestrated by none other than voldemort himself, who would use it to be restored to his body and come back to power. when dumbledore is lured from hogwarts under false pretences, harry and his friends fear that the theft is imminent and descend through the trapdoor themselves. they encounter a series of obstacles, each of which requires unique skills possessed by one of the three, and one of which requires ron to sacrifice himself in a life-sized game of wizard’s chess. in the final room, harry, now alone, finds quirrell, who admits that
