Lilith has sacrificed everything and more to defeat the Great Divine. Captured by Spiro at the last battle, she is forced to bend to his every last desire. The problem is: obey and face the Blood Oath; disobey and face his wrath. From within his lair she must confront enemies and old friends, family and forgiveness. 

Hestîa marches with Augusta''s fiercest warriors and their fearless leader, General Achilles, to pursue an alliance with the estranged community, the Vunosoï. The success or failure of this mission could cost them victory against the Great Divine, but at every fork in the road, Augusta''s errant heir lurks. 

Hanging in the balance is any hope of a world free of Spiro''s treachery and his army of beasts. If the final sacrifice is not only her life but those she holds most dear, can Lilith overcome herself to bring down Spiro?
