So, this book was a 3.75 for me. I did enjoy it as part of the overall series but for me I didn't quite feel the chemistry between the two main characters. Both are very distrustful and have been hurt in the past and it makes it hard for them to trust the other's motivations. You have Legion who was essentially enslaved by his mother and made to do unspeakable acts and then you had Tori who everyone in her life has passed away or left her and she has been raising her sister since she was 16. She is suspicious of everyone and everything and thinks everyone is out to hurt her and her sister. For this deep-seated mistrust on both their ends as well as it being a slow burn made it hard for me to see the chemistry between these two the end of the book so maybe the last 25% is where I felt the chemistry between the two.
I will say the plot outside the relationship was really interesting and is what kept me interested in the book especially as we got more background on Legion who was introduced in previous, so I was really curious as to what his story was. I also loved the new side characters like Tori's sister who were introduced in this book, and I hope with her especially we get more of her in books to come. Overall, the book kept me interested and I was glad to read another book of this ongoing series/world and see all the characters that I have gotten to know over the series again. 
I received a free ARC Copy in exchange for an honest review.
