The Water Thief by Natasha Brown
Hell hath no fury like a ratter scorned.
In a post-apocalyptic world where purified water means life and rainwater means death, ratters struggle to survive while highsiders live in luxury.
When River Quinn, a fiery eighteen-year-old ratter, is released from a decade-long sentence for stealing water for her dying father, she travels home to reunite with her mother–only to discover her mother is gone, and the very highsider who sent her to the Pen now owns her land. With a ragtag group of friends by her side, River sets out to even the score.
