Piazza giochi.

When her mother falls into a coma due to an aneurysm, 16-year-old Cassandra finds herself in the home of her father, whom she hasn't seen in ten years, along with her stepmother and a wild step-sister of the same age named Aurora. The girl is then introduced to the world of Rome's Piazza Giochi Delfici, a meeting place for young people in the area.
