In the occupied city of Tejomaya, calor_—_a magical fossil fuel—is found only in the blood rains that fall from the sky. While a six-month drought has brought Tejomaya to a desperate standstill, rumors of a secret stash of magic propel three unlikely treasure seekers to risk everything. Tenacious and street-smart Zain Jatav has been forced to steal calor for her slumlord bosses for years. Finding the magic reserve might be her only key to freedom. But she’ll have to contend with Iravan Khotar, a slumlord himself and an ambitious revolutionary hoping to use the same magic to save his people from the mysterious illness devastating the slums—and to bolster a fight against their oppressors. Meanwhile, heiress Anastasia Drakos leads the ruling council of Tejomaya from the safety of a nearby island. With the hidden magic, she could finally take full control of the city and crush the slums beneath her unyielding fist. As Zain, Iravan, and Anastasia draw closer to finding the treasure, their paths tangle, and not for the first time—they met before, a decade ago, in a fire that destroyed each of their lives in different ways. Their reunion might bring the already-weakened city to its knees. Exploring the devastating mechanisms of power, this searing climate fantasy breathes life into a crumbling world hovering on the brink of total destruction.
