Riamise is a city without water, consumed by drought, crime, and giant reptiles — the last creatures on Earth. Its people survive by earning blue crystals, the only source of sustenance. While the rich thrive, two clans battle for control, and order collapses when the police commissioner — Jona’s father — is murdered. Jona, returning home, seeks the truth behind his death and the mystery of the crystals. With Kala, a bold girl from the city’s dump, he uncovers a secret that could restore the water and change Riamise’s fate forever.
