30 of the Most Popular Books on Goodreads — We Bet You've Read 'Em All

The Harry Potter books pretty much defined an entire generation of readers, and it all began with Harry Potter and the Sorcerer's Stone. In J.K. Rowling's first novel, we meet Harry, a young orphan mistreated by his aunt and uncle who finds out, on his eleventh birthday, that he's actually a wizard. At first, the magical world doesn't seem quite so different from ours: there are friends (Ron Weasley and Hermione Granger), bullies (the ever-slimy Draco Malfoy), and sports (Quidditch). But the book quickly hints at the darkness in the magical world too, as Harry learns the truth of his parents' murders and the possibility of evil rising again.
