For real though I may make jokes but YA is great and an absolutely valuable resource for tweens/teens and isn't completely represented by the love triangle romances it's become associated with (which tbh who cares if it does have that). YA includes Holes by Louis Sachar, Speak by Laurie Halse Anderson, A Wizard of Earthsea by Ursula K Le Guin, The Hate U Give by Angie Thomas, The House on Mango Street by Sandra Cisneros, Persepolis by Marjane Satrapi, Brown Girl Dreaming by Jacqueline Woodson, The Outsiders by S.E. Hinton. And y'know I grew up reading a bunch of Sarah Dessen books, the Flowers in the Attic series, Thirteen Reasons Why, Twilight, Maximum Ride, etc etc and even though I probably wouldn't recommend those books now, they nurtured a love of reading that followed me afterwards!!! I'm grateful that people eventually realized that there is a tumultuous period between childhood and adulthood and gave that period of life a space in literature
