Vessel of Starfire

On a planet that sits at the crossroads between realms, two sisters stand between their people and an apocalyptic prophecy that forecasts the end of all worlds.
Echo and Miyala Rodrigal have lived an adventurous life of crime in the fifteen years since the elite criminal family, the Vindicata, rescued them from a home for wayward children. Once close, lately, the adoptive sisters struggle to connect. Miyala has grown into the crew's top strategist, content to scheme and plan, seemingly secure in her place within the family. By contrast, Echo feels she needs to earn her place in the crew. She's carefully built her identity around being the deadliest assassin on the continent, l'Echo Morbida, the echo of death.
When the Warlord forces the Vindicata, to betray their oath to only commit crimes of justice, Echo must reconnect with her sister quickly to find a way save their family. But the Vindicata have been keeping secrets Echo can scarcely imagine. Amidst the threat of intercontinental war, meddling gods who won't say exactly what they want, and a cult of true believers determined to strike "unnaturalness" from the continent forever, now those secrets are oozing out and Echo can't keep running from the facts about herself she'd rather not face.
