Harry Potter and the Half-Blood Prince: Harry Potter, Book 6

There's a little diversity at Hogwarts. A Slytherin named Blaise Zabini is Black. So is Kingsley Shacklebolt in the Order of the Phoenix. Cho Chang and the Patil twins are more minor characters in this book, but still around. Characters in the wizarding world face lots of discrimination, especially for not being "pure-blood," or in Hagrid's case, for being part-giant. Some diverse family structures are described: Harry lives with his aunt and uncle, Neville with his grandmother, and memories of Tom Riddle show him in an orphanage. Women have prominent roles at Hogwarts: Professor McGonagall and Professor Sprout are both heads of houses, plus there are plenty of girls on the Quidditch house teams. Some negative language around the size of Dudley and his father, Malfoy's Slytherin friends Crabbe and Goyle, plus Professor Slughorn is described as "enormously fat," and a witch named Hepzibah Smith is described as an "immensely fat old lady."

There's the death and heartbreaking funeral of a major character. Reanimated dead creatures called inferi attack in a frightening scene in a cave. A student is cursed and almost dies, others are attacked and injured in a battle with wands and magic, another is nearly poisoned to death, and when students fight each other there's a broken nose and cuts that are magically healed. House elves also fight and knock out teeth. An adult is disfigured in an attack. Another adult is nearly poisoned and hallucinates, screaming out in fear. News is always bad in the wizarding world with Voldemort back. A student is pulled out of class, told that her parents have been killed. Much talk about others killed or who have disappeared, some were minor characters in past books. News that a 5-year-old was attacked and killed by a werewolf, of a bridge collapse that killed many. Plus they mine disturbing memories of when Voldemort was younger, how he killed many, including his own father, and hanged a rabbit and tortured other children at the orphanage.

Lots of kissing among teens, or "snogging" as they call it in the U.K. Details are more funny than romantic with talk a pair is "kissing fiercely" or that it "looks like he's eating her face."

"Damn" and "hell" said rarely.

Teens drink Butterbeer (very mildly alcoholic) at the Hogsmeade pub and what sounds like slightly more robust cocktails at Professor Slughorn's Christmas party; Professor Slughorn serves Harry and Ron mead on a separate occasion. A handful of adults drink and get drunk: Professor Trelawney, the head of an orphanage, Hagrid, and Professor Slughorn. Even the Fat Lady portrait overindulges over the holidays, then changes the Gryffindor tower password to "abstinence." A potion is used by Harry and friends that makes the drinker have good luck for a few hours. The Weasley family drinks eggnog at Christmas, and warlocks are seen smoking pipes in a bar.
