If Charlaine Harris had written the Harry Potter series, the end of Deathly Hallows would have Harry sleeping in the cupboard under the stairs with the spiders and no magic.
While Voldemort would move in across the street, taunt him daily, and dispense life advice. All of Harry’s friends that he made at Hogwarts will be either dead, betray him, or not allowed to visit. Ginny would be married to a Death Eater in order to save Harry’s hitherto miserable life. But he’ll be okay with that, ‘cause he’s been thinking for some time they are too different to have a life of it.
