"My book would be Tell the Wolves I'm Home by Carol Rivka Brunt. It's set in the '80s and tells the story of a girl named June dealing with the death of her uncle during the AIDS crisis."
Description from Bookshop: "1987. There's only one person who has ever truly understood 14-year-old June Elbus, and that's her uncle, the renowned painter Finn Weiss. Shy at school and distant from her older sister, June can only be herself in Finn's company; he is her godfather, confidant, and best friend. So when he dies, far too young, of a mysterious illness her mother can barely speak about, June's world is turned upside down. But Finn's death brings a surprise acquaintance into June's life--someone who will help her to heal, and to question what she thinks she knows about Finn, her family, and even her own heart. At Finn's funeral, June notices a strange man lingering just beyond the crowd. A few days later, she receives a package in the mail. Inside is a beautiful teapot she recognizes from Finn's apartment, and a note from Toby, the stranger, asking for an opportunity to meet. As the two begin to spend time together, June realizes she's not the only one who misses Finn, and if she can bring herself to trust this unexpected friend, he just might be the one she needs the most."
