Ada and Isavel still aren't sure if they are enemies, allies, rivals, or something else entirely - but the world is conspiring to force them into a decision. Peace between humans and their inhuman neighbours is crumbling, a millenium of stasis can no longer hold, ancient gods are losing their grip on Earth, and something from beyond the world is coming. There are cities to save, curses to lift, and exiles to end. Ada must say goodbye to the few allies she has, and her time to solve an ancient wrong done to humanity is running out. Isavel must save a city that will no longer listen to her, and is rushing into a war it may pay far too dearly to win. To achieve anything at all, the two of them may need to close the gap that separates them and start anew.

Isavel has seen what comes after death, and wishes it on no one. Miraculous in the eyes of her peers and her elders, she has become the gods’ unwitting hand in an effort to stop an invasion of otherworldly creatures who would take human bodies as their own. She may fight bravely, but she is also beginning to learn that her influence may come at the cost of who she once was. But this invasion is not incomprehensible. Ada's ancestors corrupted the world this enemy is fleeing from, and so she believes the war is her problem to fix. After all, if civilization is to be built anew, the crisis threatening to destroy what little remains of it must be solved first, and Ada sees nobody better placed than herself to save the world and reverse Earth’s decline. As they both fight to restore the world, their disparate fates weave ever closer together. These gods-chosen mortals know each other’s face, but each has yet to understand who the other truly is, and the consequences of their collision could resonate beyond Earth, out into the stars that still keep watch over this forgotten planet.
