High in the snowy mountains, Alena trains harder than ever under the watchful eye of an Amazon warrior. Driven by her sister's heartbreaking choice, she's determined to embrace her destiny as the Omega and fulfil the Mother Goddess's command—defeat Emperor Tarquinius before his legions conquer the Western Lands and his greed destroys the remnants of the old gods. But when her closest allies are captured and enslaved, Alena's world descends into chaos. She soon realizes her sister's treachery was only the beginning . . .



Meanwhile, Katell, now leader of the Black Helmets, battles on the war front against the Ice Kingdoms. Wielding the dangerous magic of Laran's Tears, she is more powerful than ever, but at a steep cost to her health. When a rescue mission goes awry and she mistakenly attacks a legate, her loyalty to Rasenna is called into question. To prove her worth, Katell is sent to the besieged city of Tiryns with a single command: end the siege by any means necessary and capture the rebels hiding within its walls.



Under the gods' unwavering eyes, the sisters' paths draw them together once more. With loyalty and love hanging in the balance, they will be forced to decide where their true allegiances lie—and what they are willing to sacrifice.
