This book was a different twist on demons than I am use to reading. Mercy is a succubus demon and she had no idea until her first kiss which left her best friend lying on the floor and begging for his life. 
 The writer was brilliant with surrounding Mercy with all types of men which REALLY threw her for a loop. Her succubus side was starting to outweigh her human side and trying to take over. I enjoyed reading about Mercy's interactions with all of these boys, but I was rooting for Flynn. He is very much a bad boy and only showed his soft side a few times, but I still think that there could be something more between the two??? Luke was just too much of a goody-goody, hence what he really was which I cannot reveal, you will just have to read it for yourself! 
 The ending was ruthless and agonizing. I was not a happy camper:( The one person that I did not trust through the whole book is who is now holding Mercy's hand, but, with a sequel in our midst, I have a feeling that it may not be for long!!! 
 The storyline in this book was impressive and I really could not put it down. The writing flowed wonderfully and the storyline was easy to follow. I enjoyed the headings at the beginning of each chapter with Mercy's SAT prep vocabulary words and their meanings. I never got bored! There are quite a few grammatical errors which the author is aware of and fixing as we speak, but it did not deter me from reading and actually loving the book! 
 He leaned down and wrapped me in his arms again and patted my back. 
 I hadn't expected kindness from Flynn. 
 I didn't think this could get any weirder. 
 "Mercy, you need to choose."
