First and Foremost

《Book 1》
Nova, an angel from heaven doesn't quite fit in with the other perfect beings. After getting into trouble she meets a devilishly handsome man named Killian. Only later does she learn just how devilish he can get when he kidnaps her and reveals that he is the devil himself. Will he fall for her mischevious spirit? Will she be able to accept his evil origins? And what kind of trouble could an angel and the Devil possibly get into?
