From the description:
"LUCAS DONLON, Vampire Lord, is one of the most powerful vampires in North America and beyond. Charming and irreverent to his friends and lovers, he enjoys everything about his life as a vampire. But when a neighboring lord makes the mistake of declaring war, he quickly discovers that Lucas is every bit as lethal as he is charming. KATHRYN HUNTER doesn’t care about powerful vampires or their wars. Her baby brother is missing and she will do anything to find him, even if it means going against both her FBI bosses and the local vampire lord. But Lucas Donlon has other plans for the lovely FBI agent who’s landed on his doorstep. Waging war against their enemies and each other, Lucas and Kathryn will risk everything to keep the most deadly vampire war in hundreds of years from engulfing every vampire, and human, in North America."
