Summer in the city of roses - Michelle Ruiz Keil

All her life, seventeen-year-old Iph has protected her sensitive younger brother, Orr. But when their father decides it's time for Orr to toughen up at a wilderness boot camp, Iph is furious and storms off into the city, where she gets lost. Enter George, a queer Robin Hood who swoops in on a bicycle, offering Iph a place to hide out. Orr, in the meantime, has escaped the camp and fallen in with an all-girl punk band. In their first summer apart, Iph and Orr must learn to navigate their new spaces and find each other to try to stop a transformation that could fracture their family forever.
