I'm Myrina Holmes, the top Tracker of Infernum, tasked with neutralizing supernatural creatures who disobey our laws. In my world, demons have legions. Fourteen to be precise: seven dedicated to the cardinal virtues and seven ruled by the deadly sins. As a marginal hybrid, I belong to neither camp, which suits me just fine. I love my job and my life on Earth when I'm not on a mission. Except, of course, when mysterious corpses literally fall from the sky to torture my brain and when my succubus half-sister starts hanging out with the most detestable Hybresang there is, Kelen Wills. A supremely powerful sinner, commander-in-chief of an elite army, he doesn't embody one deadly sin. No, he possesses all seven—with a penchant for lust, anger, pride, and gluttony. But keep that detail to yourself... Anyway, this guy has made it his mission to seduce me, probably because I'm the only woman who can resist his dubious charms. This Hybresang can go to hell, because I have other midnight demons to deal with.
