Protector of Midnight. Chronicles of Midnight, #1

Not all monsters are evil. Serenity should know. She is one.Being a monster among humans is no easy task, but Serenity is determined to make it work for the sake of her adopted human sister. Being an officer with the Sunset PD means the humans are hers to protect, be it from the self-proclaimed winged messiahs of Dawn or the ravenous scourge of Midnight. But most of all from the constant threat of the hungry demon within.
But one slip is all it takes for the façade to unravel. Exiled to Midnight, a district filled with moonlight and monsters, Serenity must find her place among the supernaturals and freaks. Being drafted into the Nephilim Protectorate, the only line of defence between humans and dangerous magic, means proving her worth while battling to control her demon hunger. It won't be easy, but with the help of the protectorate men, and their terrifying charismatic leader, it may just be possible, because a malevolent force is rising, and Serenity may be the only one with the power to stop it.
Midnight's fate is in Serenity's hands, and to succeed she may have to do the unthinkable, she may have to unleash the monster inside.
