Brimstone

Duty. Blood. Honor. Power. Saeris Fane, newly crowned ruler of the vampire court, is urgently needed back in her homeland of Zilvaren - but the realm's punishing suns would likely kill her after the changes that strengthened her. She must send someone in her place, leaving her questioning whether her feelings for Fisher mean she can truly trust him. Meanwhile, Kingfisher of the Ajun Gate, despite a mysterious curse crippling his lands of Yvelia, intends to keep a promise he made to Saeris. As darkness falls, the two must journey through fire and brimstone to save both their realms and the people they love.
