The Resonance of Crystal synopsis:

When the first storm of summer heralds god-King Ashay's return to his palace in Doxa, Emmie stands ready with a strengthened heart and renewed spirit to seek answers for the questions left by Calliope. But as the uncertainty of spring melts away, something even more dreadful comes to replace it: war.

The Battle of Mixi left the province devastated. Hungry for vengeance, and with allied support from Plaines and Teshni--the homelands of concubines Cora and Lydia--Mixi's leader, Baron Rhodes, sends a letter of intent. Calliope offers a deal to stop the war before it begins, but for Emmie, who loves Ashay deeply, it's a terrible proposition; for saving Atlas may mean losing Ashay.

Meanwhile, the Other Shadow preys on King Ashay in his darkest moments, threatening to pull him back to who he once was: Change at all costs. Only Emmie can see this dark entity and bring Ashay back to himself, snapping him out of its grip.

As betrayal, war, and the Other Shadow close in on Emmie and Ashay, she must choose: sacrifice or desire?
