Say you've got a 14-year-old reader. A boy who is has started to welcome a sliver of romance into his postapocalyptic action novels, a girl who is beginning to find the Wings of Fire novels a little simplistic. Maybe you've got a formerly enthusiastic reader who is suddenly uncommunicative, a good student who is newly plagued by self-doubt, a pair of lovebirds who spend half their homework time texting each other emojis. I am trying - unsuccessfully - not to say 'ugh' to that last one. I mean, there's no harm in texting adorable tongue-stuck-out poofy pandabear hearts to your dear one, but GOD. On behalf of your future self, can I just ask you to knock that shit off? to exhibit some self-respect..?
Maybe just take a break and read a book instead? You might learn something about the way you're acting. Some kids like realistic fiction at this stage - they want examples of how other kids have tried to be cool in the face of first love, they are looking for language they can pilfer when talking back to their parents. That's helpful stuff. But there are also books that examine the darker urges of adolescence, that blow them up and play them out to pitiless extremes.
Jack Gantos's The Trouble in Me is an account of some bad decisions the author made during junior high school in Florida. And When We Were Animals by Joshua Gaylord is a sort of magic-realist novel about adolescence in a small town. Both books treat coming of age as a sacred and terrifying process, marked by blood and fire, perilous but inevitable.
