The Cloister Series by Celia Aaron
Genres: Adult, Contemporary, Dark Romance, Taboo
I joined the Cloister to find the truth. But I've discovered so much more, and the darkness here is seducing me, pulling me down until all I can think of is him. Adam Monroe, the Prophet's son, a dark prince to an empire that grows by the day.
He is tasked with keeping me safe from the wolves of the outside world. But the longer I stay at the Cloister, the more I realize the wolves are already inside and under the Prophet's control. If Adam discovers the real reason I'm here, he'll bay for my blood with the rest of them.
Until then, I will be Delilah, an obedient servant of the Prophet during the
day and Adam's Maiden at night.
