You're Welcome, Universe by Whitney Gardner
When Julia finds a slur about her best friend scrawled across the back of the Kingston School for the Deaf, she covers it up with a beautiful (albeit illegal) graffiti mural. Her supposed best friend snitches, the principal expels her, and her two mothers set Julia up with a one-way ticket to a "mainstream" school in the suburbs, where she's treated like an outcast as the only deaf student. But Julia soon learns that she might not be the only vandal in town. Someone is adding to her tags, making them better, showing off and showing Julia up in the process.
Review from School Library Journal:
After executing her best-ever graffiti, to cover up an insult written about her friend, Julia is kicked out of her Deaf school and mainstreamed. Frustrated by trying to connect with her hearing peers, Julia delves deeper into her art, only to find a rival defacing her finest creations. This debut novel is a dive into self-discovery for Julia and a compelling, engaging read for a wide variety of teens, including those interested in graffiti and street art. The author has clearly done her research on both Deaf and graffiti culture, and she incorporates details about both communities organically into the narrative. The translation of American Sign Language and Deafspeak to the page is done effectively, although it takes a backseat to native English narration. Julia, who has two mothers and resembles her parent of South Asian descent, inhabits many minority identities (disabled, a person of color, the child of same-sex parents, an English language learner) without any one of them being the engine for the story. She is a complex protagonist, and the secondary characters are well-developed, too. A few plot threads aren't fully explored, but overall, this is a well-told, artsy coming-of-age tale that is also an excellent representation of a Deaf protagonist.
