Under Control (Legion Trilogy)

We all have evil inside; some just have a little more than others. Celine Summers discovers she is half Demon with incredible powers when a terrifying creature shows up one night to claim her life. She is forced to flee with an alluring man she just met and together they must find out who wants her dead and why? In their search for answers Celine discovers there is, perhaps, a more important question. Is she strong enough to fight the inner demon, or will she be forced to lose control?
