Red Queen by Harper A. Brooks

The Red Queen will rise again…
Vampire queen Eleanna Cordon didn’t go gently into the good night when her enemies attacked her castle and stole her throne. Instead, she escaped with only her undead life and a heart that, when it did beat, thrummed for raging, violent revenge.
Reclaiming her rightful place requires more than sheer will. It demands a risky alliance with the one man she vowed never to turn to—her ex-lover and the leader of a rival vampire kingdom, Alexandru Amanar. Despite their sordid past, he’s the only one who’s ever been able to give her what she needs. In more ways than one.
But can she trust him?
Their shared history is painted with bloodshed, betrayal, and unrestrained passion, but what the queen wants, she always gets… whether that means staking her enemies or having one of them in her bed.
Red Queen is a dark vampire M/F romance set in a gothic, fantastical world. It is a standalone.
