In the near future, the Colorado River has dwindled to a trickle. Detective, assassin, and spy, Angel Velasquez "cuts" water for the Southern Nevada Water Authority, ensuring that its lush arcology developments can bloom in Las Vegas. When rumors of a game-changing water source surface in Phoenix, Angel is sent south, hunting for answers that seem to evaporate as the heat index soars and the landscape becomes more and more oppressive. There, he encounters Lucy Monroe, a hardened journalist with her own agenda, and Maria Villarosa, a young Texas migrant, who dreams of escaping north. As bodies begin to pile up, the three find themselves pawns in a game far bigger and more corrupt than they could have imagined, and when water is more valuable than gold, alliances shift like sand, and the only truth in the desert is that someone will have to bleed if anyone hopes to drink.
