The murder of 13-year-old Yara Gambirasio shocks the little town of Brembate di Sopra, Italy. To bring the culprit to justice, Prosecutor Letizia Ruggeri only has one tenuous lead — a bit of DNA that is not much help without a database to compare it to. Based on a true story.

Set in the year 2265. There is a small restaurant along the main road Galaxy Kaido, which connects Earth and the space colony Uzushio.
