Kei. Family Matters. Deamhan Chronicles, #1.5

Kei once ruled the Deamhan of Minneapolis with an iron grip. For decades, he united supernatural factions, challenged powerful enemies, and helped shape the city into a stronghold for his kind. To his supporters, he was a leader. To his enemies, he was a tyrant. Everything changed when his sibling, Selene, freed the ancient Deamhan Lucius from Limbo. With Lucius' followers gathering behind him and Kei's allies falling one by one, the ruler of Minneapolis found himself stripped of power and forced into hiding.
Now hunted by those who seek justice for his past actions, Kei refuses to abandon the city he helped build. As old loyalties crumble and dangerous forces close in, he is determined to reclaim what was taken from him-no matter the cost. Set in the world of the Deamhan Chronicles, Family Matters is a dark urban fantasy novella about power, loyalty, and the bonds that can both unite and destroy a family.
