This being book 5, and Rhys never, ever wanting to go back to hell, much less through all 9 rings has chosen to go to save humanity...again !! Little does he know that his own savior, his light to his darkness, his sweetness to his bitter, everything that will make him whole again ; Illianna awaits there for him. She has been there for a 100 years paying penance, losing her wings and being forced to blacken her soul, by the head Demons himself, and for that she hates all demons, including Rhys. As they make their way through all of the hell differing demons throw at them, they come to rely on each other in ways neither thought possible, add to that feelings of warmth, longing and lover, seem to be creeping upon them both, and in order to make it out alive, they will have to surrender not only to each other, but to the higher power that rules us all. 5☆'s of heat, love, passion, action, and world building at its best !! Better to read books 1-4 first as you get a better picture of where things stand am9ngst all the characters and scenery. This can be read as a stand alone, but you won't get the complete 360° feelings you would if you read it in order.
