Against all odds, Casia Greythorne has survived battles with gods and monsters alike, and the most powerful crown in the Kethran Empire is now securely in her grasp. Yet a seemingly impossible task still looms: finding a way to rid her world of its darkest god so she actually has a future to rule over. The path to sealing that god away has been revealed, but to follow it will mean venturing into a deadly and strange new realm, facing old fears and enemies, and deciphering ancient magic that raises more questions than answers. Meanwhile, chaos continues to spread throughout the empires. Armies rise and fall. The bonds between allies begin to fray-and hope along with it. And with every bloody battle, the final cost of saving their world becomes clearer.
