Brimstone

"Saeris Fane doesn't want power. The very last thing she needs is to have her name whispered on an entire court's lips, but now that she's been crowned queen of the Blood Court, she's discovering that a queen's life is not her own. A heavy weight rests upon her shoulders. Her ward-and her brother-need her back in her homeland... but the changes that have strengthened Saeris have also made her weak. Born under blazing suns, Saeris will surely die if she makes her way home through the quicksilver. Which means that, once again, she must send someone else in her stead. Kingfisher of the Ajun Gate has defeated armies and survived all man-ner of horrors, but traveling back to Zilvaren with Carrion Swift might just be the death of him. The male just will not shut up. Hidden dangers await them down the narrow alleyways of the Silver City. Unfolding secrets pose impossible threats. Fisher must wrangle the smuggler and accomplish his goals quickly if he wants to see his mate again."
