Harry Potter and the Sorcerer's Stone is the first in a planned series of seven books. Harry's wizard and witch parents, James and Lily, have just been killed by Voldemort, an evil wizard who was thwarted and severely weakened when he tried to kill one-year-old Harry. The murder attempt leaves Harry with a lightning-shaped scar on his forehead. Harry is whisked off to live with his Muggle (non-magical) suburban middle-class aunt and uncle (Petunia and Vernon Dursley) and their bullying overweight son, Dudley.

Fast-forward nearly ten years and chapter two begins when Harry is almost eleven and suffering a Dickensian childhood, forced to live in the cupboard under the stairs at 4 Privet Drive, the home of the Dursleys. Harry has not been told of his heritage, and is unaware of his own fame in the wizard world. He is punished when any hint of the out-of-ordinary appears, such as when he communicates with a snake at the zoo.

The narrative then follows our bespectacled young protagonist as Hagrid, the huge groundskeeper of Hogwarts School of Witchcraft and Wizardry, informs Harry that he is invited to attend the school, takes him shopping for the necessary school equipment such as cauldron and wand, and offers the first sign of affection that Harry can remember. Uncle Vernon rants and tries to prevent Harry from attending the school.

But when Vernon ridicules the name of Albus Dumbledore, the wise and beloved headmaster of Hogwarts, Hagrid hexes Dudley who sprouts a pig's tail, necessitating a visit to a private hospital. The train for Hogwarts leaves from London's King's Cross station, where Harry befriends the wizard Weasley family, who show him how to enter the magical Platform Nine and Three-Quarters.

Hogwarts has four houses, and the new first year students are placed into the appropriate house (Gryffindor, Ravenclaw, Hufflepuff, and the sinister Slytherin) by a Sorting hat. Harry's life takes a definite upturn as he finds he is a natural broomstick flyer and is chosen for the Gryffindor Quidditch team. This high flying game with three kinds of balls and seven players per team does lead to injuries. Madam Pomfrey is the school nurse and runs the hospital wing. She cures with special spells and the magic of rest.

The year at Hogwarts is filled with adventure, friendship, and danger. There are characters who seem to detest Harry, such as Potions teacher Severus Snape and a Slytherin first year, Draco Malfoy, mysterious characters such as Defense Against the Dark Arts Professor Quirrell, as well as a colorful assortment of ghosts and magical creatures. Harry and his Gryffindor friends Ron Weasley and Hermione Granger enter a quest: to prevent the sorcerer's stone from falling into the hands of Voldemort and his allies. The stone offers eternal life and hence would be key to Voldemort's plans to return to power.

During part of the adventure, Harry finds the Mirror of Erised, and mourns the loss of his parents anew as he sees them in the reflection. As the astute headmaster Dumbledore teaches Harry, however, love is more powerful than evil and death may not be the worst outcome: "After all, to the well-organized mind, death is but the next great adventure."
