The Angel's Demonic Guardian

Aeron Zero is a girl with a secret. Living the life of a presumably eighteen year old billionaire who also happens to be an Angel is easy, right? Nope, not really, and it only gets harder when Aeron starts to fall for her stunning Guardian, Gabriel. Everything would be so much easier if a lot of people and other beings didn't want her dead. And what is it that everyone seems to be hiding from her? A stubborn Angel, a loyal Guardian, a half-cat kid that's not really a kid, a female-loving incubus and two music-loving brothers, put them all in one story and chaos ensues.
